The G.F. has decided she wants a Falcon Ranchero. I am gathering information. I know I can use Granada/Monarch spindles and disc brakes. I'm trying to find a power brake booster that will work with the front discs and rear drums. Because the 64-65 Falcons didn't have discs, there is no split master cylinder specific to the model years. I'm hoping someone has already done the leg work and will share the information. Thanks.
