Started working on the Dana 60 out of a friends Cuda that could be the original but not sure. It is E Body length. We look at the internals about a year ago and it has a Power Lok and 538s. Car was run in Pro Stock in 1972 and in Altered after that. Cuda should of come with a Dana from the factory being an Original Hemi E Body. What we are trying to figure out is if it was the original to the car or swapped in during its racing Career. So here are the numbers on the right axle tub and we are trying to find the internal pictures for more casting number information.

Dates 6 19 0A2 , 7 16 0 78. BOM 603226-4. My understanding is the first two dates are like casting and assembly dates. The BO number tell me it is a E Body 410 from the factory. Now being such a late build in 1970 did Chrysler use up late built Danas in 1971. The Cuda has an SPD in April, I think 406 to 409 or very close to that so would this Dana sit around for 9 months then put in the Cuda. I know this were getting tight with builds in 1971 so maybe this Dana Rear End is original or maybe not. Going to take it completely apart and add axle, spool, another gear and lot more go fast stuff.

Any opinions just start typing.

BOM shows 1970 with 4.10 so it’s not a Direct Connection unit.

What’s the chances of getting another factory Dana in this car?
Unless I am missing it, I don’t see what year the car is. Some of the number geeks can chime in but I would think there should be a month or more difference between vehicle build dates and axles - axles built before the car of course.

Car is a 1971 Hemi Cuda and has been a race car since day one. Raced in the summer of 1971 as a SS/D and then in 1972 as a Pro Stock and 1973 and up it was raced in C Altered and then parked in the late 70s. I believe the rear end is a late 1970 build but might of been used in 1971. I have never looked at the lead in times for this Rear Ends. I know Hemis Blocks in 1971 and are all over the place from 1968 to 1970 casting dates but assembly are also sometimes months or weeks before the build date of cars built in 1971 no real set pattern. This Dana has had a gear change from near day one and in the picture we took will look at there date codes. I know from my June built 1971 Hemi Challenger that the 1971 Dana under GOOD HP does not last. My Dana did not make it 6 months

Also is there any other 1970 or 1971 Specific things like brake hoses, emergency brake cables. The spring perches have been moved from the stock location and line up with the frame were the spring now go..

I don’t think the assembly plants ran much different than they did up to the late 90’s when I used to get in to them.
While there was some intent to maintain FIFO, there was no guarantee they did.

I don’t personally see it being hard to have a late built 70 axle in a 1971 vehicle if the part numbers remained the same from 70 to 71 like this axle does.
If the part number was unique for a given year the plant was supposed to clean out prior model year stuff and not use it for subsequent model year production.

Assemblies usually got sent to Mopar for service.

Ya I put my 30 plus year sentence in automotive production. Seen a lot of thing done and got a few odd things done also. FIFO was one thing that Chrysler tried to do but with Hemi Blocks there was a room were they shoved the Castings, The date is on the sideof the block. They on the bottom of the pan rail there is a Machining date. Then if it got assigned to a Year when the Machining was done it had that years letter and assembly numbers.These numbers on the bottom of the oil pan rail that never got a year stamp have a quantity stamping number telling what year they were machined. Each year have a certain number that was started at and ended at for the machine of all blocks. My Challenger has a casting date of around 7-??-69 and was machined in early 1971 and assemble in 1971 maybe two months later and the Car was assembled in June of 1971. Iwould have to take a look at the block again to get exact dates on the motor, the original block just sits in the corner of the garage and has not been back in the Challenger since the Winter of 1972. Being a race car you amass motors and parts to use when drag racing and I am looking again to up grade the Cubic Inches.

Getting back to my question I think this Cuda might have the original Rear End in it. I have seem things get pushed back on a skid and sit for along time. At were I worked I finally got the plant to use up 3 year old Spare Tired Rims that sat and sat and no one esle did anything about it. They were the same as the present rim but had a 3 year older date code and they finally agreed to have me put them on the line for use. So if this was a 1970 rear end maybe it sat and finally got shoved into this Cuda. I know of a 1971 HemiCuda also built at this time April 1971 that has a 1970 Shaker hood on it originally and have seen one other shaker on a Cuda that has a 1970 Shaker Hood built in April. Did Chrysler want to get rid of these hoods and a good place was on a Cuda or was stock low and pulled hood from a parts warehouse. You would have to be there to know.

Assuming you were a line worker in the early 70’s and you were 30 at the time, you would be in your early 80’s now. Those people are the ones that may be able to tell us how things ran, but likely many are gone, and certainly are not on these forums. And probably couldn’t care less about how things ran back the next if we could speak to the them. shruggy

So why worry about it. Sounds to me like you want to make it come original from the factory in this car but odds say it never did.

Just trying to see what it is. This car will never ever be restored to some trailer queen 1971 Hemi Cuda by us, but knowing what it is makes it easier to built the car back to the Pro Stock it was. Likely will only use the housing, thought about using a B Body Dana also since we have a few of them and an extra 1970 E Body Dana. Deciding on the length of the rear end decided the off set of the rim we will buy. This Dana will never survive the HP the Cuda will end up with so that is why the housing is the only thing in the next 3 month will be used. All that we learn from looking at this Dana might help some other person on their restoration and I have another 1971 Cuda with a Dana and will be looking at it comparing the numbers. It is all a learning curve to amass information for us and other to look at.

Nice car indeed you have there!

I was lucky enough to work on some 70/71 hemi Cuda converts back 20 years ago.

Block castings were “all over the place” as were axle BOM’s.

So restorers who have extra parts tend to ‘right factory’ mistakes...
Obviously engines and trans are not changeable but other parts are.

The weirdest one I saw was a late 70 Dana in a 69 built sixpack Challenger?

How and where did it get changed?

My guess is the power lock axle was swapped for a track lock... drive spank

Power locks OK for 600hp

Track locks only 400hp according to Dr. Diff etc... fan

Thats a powerlock. My red 71 440-6 4-speed cuda had a 410 powerlock. Oct 70 build. On the shaker hoods I am pretty sure they used what they had. Every 71 cuda I ever had with a shaker was a 70 hood. When we had our shop I bought the shaker off of a brown 71 4-speed 383 cuda from texas in the 80s. Not sure on the exact build date but it had billboards, rear window louvers, and the gullwing so not an early car, it was a 1970 hood. Guy needed $$$ to get home but would not sell the car or louvers, wonder if it still exists. On danas my worst example is my 2000 diesel pickup, it has a 1995 date housing with a powerlock, I bought it new and it is untouched. The stuff does sit around, I figure they went to rear disc in 2001 so they used them up, 71 cudas were probably similar, only what about 300 got a dana if that many, from what I am told all 71 e-bodies are traclocks, mine was not. Kinda funny we were just talking about this last month, I sold my 6bbl cuda and told the new owner not to believe everything you hear about 71s.

The E Body build year is a mixed up bag. The first 1971 Hemi Cuda sold new in Canada has a SPD of 926 Sept of 1970 and that car has a lot of 1970 parts on the Cuda. 1970 Hemi Rad, 1970 Shaker Hood and a bunch of other 1970 parts. I know of another a 1971 Hemi Cuda early build that came with a 1970 Wing. All early build E Bodies did not have the Asterisk before and after the Vin Number on their Dash Vin Plates. The second 1971 Hemi Cuda sold new in Canada with a SPD of Nov 5 1970 has all 1971 parts, hood rad etc. and had the Asterisk on the dash tag. I believe Chrysler was getting rid or their 1970 parts onto the1971 E Bodies at the start of Production in 1971. You also have screw ups were it says that a 1971 Hemi Challengesr could not be ordered with an Automatic. 14 were 12 US and 2 Canadian, most of the USA 1971 Challenger with Hemi Automatics were early orders from Mr. Norms.

Looked at the inside of this Dana today. It looks like on the Sure Grip that it has a September 1970 date stamped in it. So that would likely mean this rear went into a 1971 E Body not a 1970 E Body.

Thanks for posting on this and any more information would be great.

I would guess a very late 70 car, as the 71 cars got the track-lock?

My dana 60 is a late 70A axle but has the track lock in there, 603226-4 is an E-body 4.10.

At my uncles Dodge dealership in the early spring of 70 Mr Pitts came and ordered a 70 Challenger RT/SE Hemi auto purple. Was trading in his 68 Hemi Charger, so I told my uncle the 68 was mine when his new car came in. Fast forward 10 months (spring of 71) the car came in on the trailer (a 70), i was the new car pre-delivery guy and was sure I was going to drive that car, nope, Mr Pitts came and drove it OFF the trailer himself. In the meantime I had already bought a 70-1/2 Z28 (in Dec 70) waiting on the 68. Hard to believe that the 70 Challenger came in that late.
PS. A friend (3rd owner) begged me to buy the car in 75 for $1400 and I passed, 1 of 25 or something, but who knew then. Like was said anything could happen with a Hemi car that late in the game.

Someone installed that particular power-lock. 5.38 gears require a carrier change as an OEM E-body Dana 60 was only available with a 3-series sure-grip.
