Thx Pat. This is interesting. I was looking at the second item you posted. Right now I have 4 drums with a single reservoir MC (non boosted). As you can imagine, for safety, I want to upgrade to a dual reservoir asap and figured while I was at it, get a boosted unit. So I picked up a MC conversion kit for my car that came with a dual diaphragm 7" booster, dual MC and all the necessary bracketry. The kit states it is ok for a drum/drum or a disc/drum set up. Due to funding, I'll stay with drum/drum for now but will be swapping out my front drums for discs asap. I am trying to make sure I have all the pieces in place now to avoid headaches with my future plans for this car.
I think I am on track, but welcome the advice.
