My brake master just crapped itself. Looks like its leaking between the booster and MC. None of my local parts suppliers can get one until the middle of next week. I've done a couple of searches to see what other MC's can be swapped in, but most people are swapping MCs when they're doing disk upgrades. Some have used a supra, early 90's pickup w/v6, or 80 series MC. Can anyone tell me which, if any, MCs will work with my 78? It's my Daily driver, so, I need to get this fixed this weekend.
