It appears that I have a leaky master cylinder. Whenever I've had to replace a part on this car I have tried to find an "upgrade" and would like to do this here, if possible.

I've priced master cylinders from Advance Auto as well as Pep Boys and I'm looking at anywhere from $70 to $150, rebuilt vs. new.

I've also noticed in Summit's catalog that Wilwood offers a master cylinder. Their website gives the dimensions, but doesn't have an application guide. I contacted Wilwood through e-mail, but didn't get a response.

Has anyone installed one of their master cylinders on their LT1? Can I get a direct replacement, or will modifications have to be made? Can I retain my ABS?

Thanks,
Joe
