This was taken from another page

here is some part link info and alternative drum info from the archives in 6066 GMC site. Hope this helps.

To view some links or images in this forum your post count must be 1 or greater. You currently have 0 posts. Maybe you should introduce yourself with a new topic? Centric Parts 122.66037 Brake Drum: Automotive

The front drums are easy. They are the same as a Chivy and should be easily found and are relatively cheap. They have a 3" height or depth. Here's's listing.
RAYBESTOS Part # 2005R $33.79

The rear drums are a bit harder, but I have three part numbers you can try for rear 6 lug brake drums. These have a 3.5" height or depth. The first is CENTRIc Part # 12266037 . The second is Allsafe 2067 DGS or Raybestos 2067R. shows the Raybestos 2067R for $58.79. also has the Centric Part #12266037's for $119.79.

I used the Allsafe 2067 DGS from Autozone. The 2067's are 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 Chivy drums.

On the Centric, I haven't used that one, but was told it was a direct match to the original (a bit pricier though).

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