37 pontiac master cylinder rebuild kit interchange?

Hello all!

i'm trying to get my master deluxe on the road!! i need to rebuild my master cylinder! does anyone know if it is true that master cylinder rebuild kits for manual master cylinders are interchangeable from 1937 all the way to 1966? they all look very similar. unfortunately, i do not have any part numbers to compare against. thanks in advance!

 

Not hardly !! MC bores ranging from 7/8s to 1&1/4 depending on year and make.

 

oops! well, i'm bidding on a belair MC rebuild kit for $10ish dollars. my current mc (from what i've read has a 1 inch bore. i guess we'll see what happens. i guess i'll start looking for an appropriate one then. wish i knew the interchanges, though. thanks for the help!

 

For Pontiac 37-54, 55-57 very similar. Try California Pontiac Restoration, they show a rebuild kit for under $20 for manual brakes .
