The "A" turned out be yellow and a "B" revaled it self. The line on the left is a green slash???

Some of the 8 3/4 markings. Its a 391 sure grip.

I got quite a bit done today. I was able to get the motor and trans off the dolly and onto carts. Before I did I cleaned up the back of the motor, the bellhousing and trans. Somewhere along the line the orig owner painted the trans black, which luckily preserved a lot of the markings. In this pic you can see a blue 751 & orange blob on the side of the trans. The orange engine overspray on the bellhousing is also obvious along with the runs.

Once I got the u bolts cut off I was able to clean the under side of the 8 3/4. Which revealed a 9140 & 914 on the rear and diff. It also seems as if there were orange and black marks on the bottom of the diff.

Lower axle tube. Can't really make out whats on the spring perch though..

My neighbors love me! Actually I do most of my work during the day so they aren't there to care. Not to mention they tore out their front lawn to put gravel in so they could park 1 or 2 5th wheels there so relatives can live in them periodically..

I went to take the starter off and it was stuck/ rusted onto the top stud. After sitting overnight with several coats of oil I was finally able to pry it loose. I was hoping for it to be the date coded original starter, as it worked well. Nope it had a 1975 date code...damn I'll still probably get it rebuilt though.

I was surprised that my water pump and alternator appeared to be the originals as they were dated correctly. Not sure if the starter was but I have that too. Someday I might rebuilt the original mill. Your attention to detail is great

The colors blobbed onto the bottom of your 8.75 center cection signify the gear ratio. Odd that the tranny is painted black, have you checked the VIN to see if it was swapped out? Maybe just R&R'd the original for a leaky seal or something? Be sure to get pics of the orange overspray pattern on the bell housing as well as the location of the wire clips, etc.

Good stuff, thanks for sharing!

that is the cleaniest rear end I've ever seen, way too smooth

I was waiting for the B to show up on your axle, thats whats on my 71 demon.

I have a picture of an trans with the same markings I just don't remember where it came from

The rear end is so smooth from all the rubbing and scrubbing with steel wool and dawn soap. I was surprised with all the markings that showed up condisering the only one that could be seen faintly was the "A". Probably doesn't hurt that the car spent a lot of its life in San Diego & 15yrs under a canvas tarp too.

I'm guessing the orange and black markings denote 391 gears? I have a chart I can dig up about that. I never realized the diff and rear were assembled the same day though (9/14/70).

The orig owner swears the trans is the original one it came with and it was never rebuilt, although he say he went through quite a few clutches! The VIN is all messed up on it, although 6bblgt was able to make out the VIN 115059 I knew it was messed up when I bought it and but its not a deal breaker for me, the car is what it is. Its going back in that way, and won't get restamped

If I'm reading your date code correctly it decodes as (P833 3338 XXXX)September 17th, 1970, the trans in the above photo is mine, yes, it has some of the same paint markings as yours by the looks of things.

SPD is OCT 14 1970

Based on that I'd guess it's your original trans. It's not likely that someone hunted down a replacment with the right assembly date back when that car was on the road


Post a nice clear pic of your engine stamping as well as your body stampings if you have them (or just e-mail them to me if you prefer) I can probably offer you some further info on the trans stamping if you do.

*Also, can you post a pic of the date codes on your Rallye wheels? (dates are stamped right near the valve stem holes) Do they all have the same dates or not?

Heres the block VIN The car is at the media blaster and I don't have any body stamping pics that I can upload.

I've only got one rally unfortunately. The slot mags have been on it since 72! Heres the date off the one I have.

Good stuff, that wheel date aligns perfectly with your SPD, engine stamp also looks legit. The trans stamp is likely a bad try bouncing attempt, the LA plant workers seemed to have more issues with transmission stamping than other plants, I've seen a bunch like yours in recent years.

If you feel like investigating and sharing further here are some more date codes I'd like to see/know.

1. Jack mechanism (one of the rivots holding it together will have a two digit code)
2. Hood latch release mechanism (date code is stamped into the verticle face)
3. Wiper motor (stamped into the gold colored metal barrel housing)
4. Radiator (digits are stamped into the passenger side mounting flange about 1/3 way down from the top)
5. Intake manifold casting date
6. Exhaust manifold casting dates
7. Steering box casting date
8. K-member stamp date (located in the very front center verticle surface, often shallow and hard to read)
9. Lower control arm dates (numbers stamped into two forward facing rivot heads on each)
10. Water pump housing casting date
11. Bell housing casting date
12. Temperature sending unit date (2 digit code stamped in tiny digits on the side)
13. Oil sending unit (2 digit code stamped in tiny digits on the side)
14. Date codes on the side view mirror glass

No problem Scott. I can't give you 2 & 3 as Jules is making them pretty right now. Also 1,6,& 10 are missing or have been changed, but all of the others I will get tomorrow.
