Rear Brake drums needed for a factory posi dana 44

Its a factory positrac 2wd half ton, and he says it needs to be offset a half inch to the inside to fit properly. Normal rears are supposedly straight up and down. Anybuddy have any info on the differences or places to find a new, correct rear drum? Any infro appreciated, thanks guys.

I assume you've checked and the drums for the Dana 44 are different than the ones for the 12 bolt? I've never worked on a Dana 44 rear differential, but it wouldn't surprise me if the brakes were the same.

Re: Rear Brake drums needed for a factory posi dana 44

Walt:
The GMC's used the Dana 44. Here is a summary of my search for brake drums for my 1966 GMC with 6 lugs.

I have two part numbers you can try for rear 6 lug brake drums. The first is a Wagner BD 60089. The second is Allsafe 2067 DGS.

I used the Allsafe from Autozone. It is for a later model (I think 67-72) truck with 4 wheel drive. It has fins on the outside unlike the original that is smooth. The only modification that I had to make was to drill the 6 lug holes from 1/2" to 9/16" so that the drum would fit on the shoulders on the rear lugs like the original. This drum had the right offset unlike the Chevy drums.

The Wagner was a number that I got from another member of the 6066gmcguy.org site. I haven't used that one, but was told it was a direct match to the original (a bit pricey, though is what I remember).

I hope this helps with those looking for rear 6 lug drums.

Regards,
