1/2 Ton Rear Drums with Part Numbers

[truckster]

I just completely replaced my rear brakes and thought I would share the part numbers in case anyone is looking for them. My specific vehicle is a 1972 K/5 Blazer, but this should work for any 1/2 ton.

Brake Drums - GM 89058331 / AC Delco 18B471
Brake Shoes - GM 19307571 / AC Delco 17280B
Brake Spring Hardware Kit - AC Delco 18K1597
Brake Adjuster (left) Raybestos H1530
Brake Adjuster (right) Raybestos H1531
Brake Spreader Dorman 21149

There were a couple of small things that weren't included in the hardware kit, particularly the brake adjuster return spring (the one that goes between the adjuster and the inside of the shoe). The drums are a more modern design than the original ones (see pictures) but the dimensions are exactly correct and they fit inside my rally wheels. The brake spreader is a little bit wider than my stock one, but it fits perfectly. It's nice to have rear brakes again.
