Disc Brake Upgrade Reference Thread

i grabbed the whole front clip from an 85 c10 this weekend for my 64 and will start tearing down, cleaning, painting and stuff like that - couple questions

i plan on getting the DJM 3" drop spindles, can I use the drop coils i got from CPP that Im currently running in my 64 arms?

there is a valve on the 85 that mounts ahead of the x-member - is that just a factory proportioning valve or is it the pressure differential switch? It has some electrical connector that I have no clue about - should i just replace with a basic prop valve or what? i dont have anything from my harness to connect to it

the shim stack used on the upper arms is unreal - like 8 or 9 per side - any ideas why they would need to do so many? dude says oe spindles and stock coils??
