Need replacement master cylinder for 1962 Rambler

Thanks for your reply I actually find a company that do not only rebuild it but they'll actually replate the outside for $195

And sometimes that's the "best" way for a driver. If the 62 uses two bolts to mount the MC it's easy to convert to a newer model. If it's the old four bolt type it's a bit harder -- you have to drill two holes for new bolts and remove the four originals. I've seen it done, but not done it myself. You sometimes need to make a custom length pushrod when doing a conversion. That can be tricky -- too long and you lose a lot of pedal travel, too short and not enough (or it pulls out under dash!). I've done that and not had any trouble. I just make it slightly longer than I expect I need, then trim it down a little at a time. PITA to remove/trim/install/test a few times, but better to have good brakes!
