70 E Body brake parts

I need to get all of the hardware for my e body rear brakes, I know I can get a majority of the parts from autozone etc. What I can't get at autozone is the parts I have have pointed in the pic below and the two pieces that go into the wheel cylinder. My question is this what other mopar products can I scavenge these parts from that I would still find in a scrap yard

Probally and 11 inch brake set up from a Mopar.Usually the later C body and Imps and Van/trucks have 11 inch rears.Rocky

the cylinder shoe retainer plate should be the same on all drum brake B,C,E bodies,truck,wagon, van and imp. but the e-brake equilizer is different[length]between 10" & 11" brakes, so what size you have matters ![ ]
