Master cylinder conversion

Richard Lacy uses 15/16" in his kits.

We use a 7/8" MC on our 1932 kit BECAUSE of the over-all pedal ratio resulting from our design. We use 1-1/16" on 33-34, 35-36 and 37-38 kits. If we install a "dual" MC on 33-34 we are stuck with a 1" which is not ideal due to the increased pedal travel required. We do have one with built-in RPV's and LH outlets.
