Hi all. I'm totally re-doing a '57 Olds Super 88 and have a few questions. First, how do i R+R the "Fuzzies" in the front (Flappers) and rear upper window weatherstrip retainers. They look like they're manufactured in. And has anyone put a firewall mounted Master cylinder and Booster on a '57? Do you mount it below the Cowl Drain? Many Thanks in advance! Charly9g wfg4u@aol.com
