to install the Z32 MC, its alot of work. If you are a rookie DO NOT DO IT. First you would have the destroy your old MC and take the thread out from one of the lines. And insert it into the Z32 MC, beninding brake lines, there is alot involved. There was a write up on it.
P.S. I CANT STRESS ENOUGH HOW IMPORTANT IT IS TO USE AT LEAST DOT4 BRAKE FLUID. ITS VERY VERY IMPORTANT.
