Problem with '74 'Vette master cylinder
The master brake cylinder on my ride leaks, so I figured it was time to replace it. It's the classic '74 'Vette master cylinder. (the casting number on the body is 29969).
So I went to NAPA, got a reman m/c (with casting number 29969), but it's notteh same part.
The cup where it receives the rod from the vacuum booster is shallow, whereas the replacement part is deep. The other m/c's that NAPA has have a deep cup.
Is this a power/manual brake difference? Am I confused? Is NAPA confused?
