I recently purchased 1.125" Wilwood MC for my GN (see signature for brake description). Anyone done this install? Do I use the spacer or not? Looking at the MC that I have been running, I see the plunger is flush with the opening and, if I use the spacer, that is what I have with Wilwood so I'm assuming I'm right. Instructions say, "For short push rod power brake boosters, use the spacer supplied to reduce the overall depth of the piston recess."
