I guess I'll kinda answer one of my questions...After some more browsing I discovered (thanks to the tech section here...Doh!) that a mid 70's Chevy 1/2 ton truck MC will bolt up to one of the common adapter plates...I assume a 1 ton MC from the early to mid 70's will bolt up too. I'm not sure about using a MC meant for up front discs on a full drum rig though...Did Chevy make a full drum 1 ton with a dual reservoir MC at any time?
