I would recommend the Dana 60 solution. You should be able to reuse your 35 spline axles and brakes. Truck Dana housings are easy to find for less than $200.00. Make sure the side carrier bearing has not spun in the housing to avoid additional machining costs (common problem, easily fixed). You will need to buy a new spool, bearings, seals, gears, companion flange, housing ends, ladder bar mounts, and shorten the driveshaft, but altogether (with your existing axles and brakes) you should be able to permanently solve your rear end troubles for less than $1,000.00. Check with Dr. Diff on prices. And you could sell the 8&3/4 carrier and spool to make up for a lot of the difference. And once you have a bullet-proof rear end, you can almost forget about the major reason that 727s explode.

This

We run this same set-up, 30 spline axles even. We have been 1.28 60ft (no transbrake) and our rearend troubles are gone. We twisted a backbraced 8 3/4 and broke multiple pumpkins which led to broken sprags.. Once you add more power you will be glad you went dana..

And from what model truck should I get a cheap housing and best supplier for parts ?
I take it the Dana from trucks are sufficient ?

If you can find a truck or van dana 60 housing that has the three (3.0) diameter axle tubes buy it quick take your time looking, if you can't find one of those then look at buying the next size axle tubes that are 3 1/8, some are even 3 1/4 diameter , I would stay away from them BTW some fo the GM and GMC early(1970 and earlier ) 3/4 ton pickups had those and I think even some of the early Dodge and Ford pickups had them also. I'm not exactly sure when Dana Corp. started making the Dana 60 with 3 1/8 axle tubes

Will I be able to retain my 35 splines axles from my 8 3/4 ?

I had Strange 35 spline race axles special made to work with the stock A body 8 3/4 housing with the strange 35 spline 8 3/4 spool, I twisted that rascal(houusing) up horribly with no back brace. I swapped the axles over to the truck Dana 60 I had narrowed and I had to cut about 3/8 inch off the end of one axle, so yes you can reuse your 35 Spline axles in the Dana 60 with the 35 spline Strange, Dutchmen, Yukon and many other spools Make sure and check for end play, don't let the axles butt in the center The exception might be the Mark Williams 35 spline spool with thier different axle and spool teeth angle, 30 degree versus maybe 45 degree angles, not sure which one is which

Yes you can, you have to put 8 3/4 ends on the dana. Brakes will work too.

Duh !! of course it will fit ! loll haven't thought of that so far lollll

Cab burge is saying my spool will fit in a Dana ???

---

NO Not even close, sorry But your 35 spline axles (brakes and brake drums will fit on the new ends also) in most 35 spline spools BTW, make sure and mark your axles(right and left) when you take them out of the 8 3/4 and put them in the new cut down Dana 60 on the same side thay came out of so you don't try and run them backwards to what they've been run already

The 8 3/4 Moser fab housing is a nice piece BUT they are a pain in a A-body with a stock fuel tank and fuel lines, everything is very tight.
Also if you have the tubes braced on the Moser you will need to have the braces notched so the shocks fit.

That's what i use

if u were closer i'll buy that center sec.

8 3/4" housing and ALum. Centre section, and really good gun drilled 28spline axles and run mid nines

put a dana in it and forget about having issues with your rear...

---

I put a 9" in my car only because I can swap out the carrier at the track if I have to and parts are easy to get. again I wouldn't sink money into an 8.75 with anything over 450hp and definitely not with a stick car!

Sorry OT, I'd love to know more details on your "gun drilled axles"

Me too why would you drill a 28 spline axle

Hi,
My whole car is all weight revolved!! So I ordered mark Williams 28 spline good axles and had them machine out then heat treated!! Plus ring gear is cut back for weight!Killer strong and could put any centre section gear swap in anytime! Run a Detroit locker as well, no spool. Car is a true street car!
Helps that I have a good friend that does this kinda stuff!!
All steal body with stock glass, but sneaky lighting parts to make the car lighter, but look stock!!
Lol, it's just me!!!

I've never heard of any 28 spline Mopar axles for 8 3/4, let alone a 28 spline spool for the Mopar 8 3/4. Ford nine inch yes, but not Mopar 8 3/4 Your not a keyboard racer, car builder are you

I went with a Dana.....
With the engine dynoed at 606hp, I''ll be sure it won't happen again !

If I add a 200hp shot of nitrous, that will be a killer on the 8 3/4 for sure.

I won't go there again

Good choice

Can someone explain the differences between 2-series and 3-series gears ?

Hope I won't run into any problems putting a spool and 4.56 gear !

---

Dana 60 never came with a two sereis gear, only down to 3:54.The Dana 61 came with 3.30 gears. The two most common Dana 60 carriers and spools are three series or four sereis, the three sereis works on 3:54 to 4:10 stock Dana brand gears and on the U.S.(Strange house brand also)4:30 ratio. The four sereis works on 4:56 and above on most Dana gears and most after market gear sets, not all though When it comes time for you to buy a spool and gears make sure they are matched (same manufacturer if possible or same vendor )and intended to be ran with each other I just went through the hassle of trying to find out what U.S. Gears, 4:30 ratio, fit on which sereis 40 spline spool U.S Gear reps didn't know, U.S. Engr. didn't know They said to call Strange, Strange had already told me to call U.S. Gears I ended up calling a guy in Montana that use to own a rear end shop(J&S) in SO CA years ago and he said that the U.S. 4:30 gear sets will only fit the 4 sereis 40 spline Moser spools I bought a new one(40 spline steel spool) but I haven't swapped the 5:13 and Mark Willaims aluminum five seresi spool out of my new race car yet for the 4:30 and new steel spool, so I'm hoping he's correct IHTHs

Sorry,
my mistake meant to say 30spline axles!

I thought maybe you might be confusing the Ford nine inch parts with the 8 3/4 parts
