Replacing M/C on KZ750 LTD

Okay so here is my issue. I can't stand the Buckhorn Handlebars so i ordered a super cross bar. I realized the original M/C connects to the handlebars at an angle. I am wondering if there is a certain M/C to replace this with or at least one that will attach and keep the fluid level. Never had to replace this so i'm just wondering what i should be looking for.

Sorry I placed this is the wrong category. not sure how to move it now.

usa-motorcycles-inc on eebbaayy lists various aftermarket Fr Br master cylinders. You should probably get one having a 16mm piston bore for dual disk. You'll have to splice the brake light wiring, which shouldn't be a problem.

Other M/Cs: you could use one from other Japanese motorcycles which have dual disk & a similar piston bore.... Kawasaki, Honda, Suzuki, or Yamaha. Some don't have a mirror orifice.
