" I've got a torch and welder, we can make it work." My roadster has a C4, SBF and hanging pedals, booster on the firewall . Most of the time 40 and later hydralic parts were swapped in, mounted under the floor. I don't know how much work is required . I plan on doing a total rebuild of my roadster, and haven't decided on a lot of things yet. If you google model A brake upgrades you might find out more.
