Buick Skylark 10 Bolt posi casting code 1385724 3-N

Postby pinwhhelx » Tue Oct 07, 2014 8:24 pm

Hello,

I have read some of the post about these. Mine was taken apart by a rear end shop and I was told it has an early style bearing tappered I Think? With a large axle? Current ratio is 3:23. he and i have been unable to source parts. he thought it was from a 61-63 Buick. is this possible with that casting code? Received gears and they would not fit to big was told none available?

Can anything be done with it to use it? Would like to see it in 68 LeMans.

Well actuall I JUST SAW you had the casting number which is a 1968-1970 10 bolt 8.2 Buick rear so really no need for pictures. We usually have people post pictures of the rear yoke and backing plate area as we can actually tell you what model year rear you have just from pictures if you do not have casting numbers. Jim

To posy pictures you just hit the upload attachment gray rectangular button under the post reply box where the text goes. You can browse your computer for the pics you want to post and just follow as the computer guides you.

We have all the parts for this rear. We have rebuild kit which includes the following parts
2 carrier bearings and races
1 inner pinion bearing and race
1 outer pinion bearing and race
1 Pinion seal
1 pinion crush sleeve
1 pinion nut
1 rear inspection cover gasket
1 carrier pack of carrier shims
1 pinion pack of shims
1 marking compound and applicator brush
10 ring gear bolts
1 booklet to help you with your set-up pattern and torque specs.
Axle bearing and seal kit we will need to know if you have a seal IN THE AXLE TUBE END or the seal ON THE AXLE SHAFT out board the axle bearing and inboard the retaining plate
We do have gear sets 3.42 and 3.64 (these are CUSTOM and only 30 are every made at one time. Seems we only have 3.42 on the shelf and they are not cheap)
Posi units - we can get you 2.56 2.73 2.93 3.08 3.23 3.42 posi units NEW
We can custom make 3.64 3.91 4.30 4.66 series posi unit cost will have to be estimated as there is machine work involved.
Axle shafts We have axles shafts for the rear (except for 68 69 GS and WAGoN)

That should cover the 1968 1969 1970 Buick Skylark, Special, Special Deluxe, California, GS, Wagon etc.
