Leaf spring rear

[67gmcclassic]

I have a 1967 GMC c1500 2wd with a dana 44 rear axle with leaf springs. I am having a hard time trying to find replacement brake parts for the rear. All the listings are for a gm 12 bolt rear-end, with coils springs. Are they the same rear brake assemblies for the dana 44 and the 12 bolt chevy rear end. I didnt think it would be hard to find parts for this truck, but i am having trouble with these rear drum brakes for the dana. Has anybody run into this before ( im sure someone has). Any help is appreciated, and part #s would be even better. Thanks
