rear brake drums - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I have a 81 GMC 2wd 1/2 ton donor truck to upgrade my 69 to PS/PB and it looks like the rear brake backing plate will bolt on to the 69 rear. What I want to know is would 81 4x4 drums match up with the backing plate?

Also, if I swap the 69 rear for the 81 (lot of work) would 4x4 axles fit the 2wd rearend?

The drums and discs are shot, I bought 6 lug discs from GMC Pauls for the front conversion and would like to upgrade the rear also. Trying to get some ideas/options before I head off in a direction I'll regret latter $$.

Thanks
