Re: Buick "B" BOP from 68 Skylark

Yes the 10 bolt 8.25 68-70 Skylark rear center section GUTS... Meaning the ring and pinion and posi or open carreir can be interchanged into to a 68-70 8.25 Buick LeSabre rear end.

YOU must use the Lesabre axle you can not use Skylark axles...They are too short in length.

Re: Buick "B" BOP from 68 Skylark

Most all axle bearing sold today have the retaining ring with the bearing.
the part number will also tell you if it has the retaining ring
IE
RW507C No retaining ring
RW507CR includes retaining ring.

The R stands for retaining ring

Re: Buick "B" BOP from 68 Skylark

do you have the casting number ...does it end in 700 or 724?

Any other pictures of the rear?
Does the carrier have a larger driveside bearing than the passenger carrier bearing diameter?

Re: Gearing and Posi for 8.2" 'B' Buick Skylark Rear

We did aid in getting these 3.42 and 3.64 gears produced about 7 years ago. Things have happened with the manufacture of the years and they have been bought out and it will take some time to get on their feet and running gears. We just have to wait and see what happens at this point. Used 3.42 gears...

Re: 69 Lemans Safe T Trak

Yes will PM you with all the info
If you send it with the ring gear attached...PROTECT it well.

We will need to remove the carrier bearings so might be smart to just get NEW ones installed after the reconditioning. We will get you all the prices in a PM
