Some snags with my conversion

I had three questions rammed in there, first one I will take a pic of later of where i need to move my brake pedal to. The clutch pedal is much lower than the brake, can I simply adjust the rod and then manipulate the brake switch mount to match?

My combo is 71 Duster, 440, A833, Mcleod clutch and Mallwood hydraulic under dash pedal system

The hydramax question. The collar spacer they give you is too thick, and they don't give you enough shims to just use shims to get your .150 gap. How have people solved this is what I am asking? Can a hardened washer of the same ID be used as a shim? No hot rod shops up here carry shims.

I had mentioned ford because someone on here referenced replacing the Chrysler collar spacer with the Ford one because its thinner

Also on the hydramax, its the only bearing that comes pre bled, does that change the gap requirement?
