So I need a booster from an 80-up 2wd. I did the disc swap on my 72 and tried to just buy the later model master and it doesn't bolt properly to the the booster. Needs 2 bolts instead of 4. So I went with the rebuilt 72 master and it doesn't have enough oomph. So I have the master, just need the booster and I can trade you back a brand new OEM rebuild 72 master if you want one
