Running into some problems, I have everything I need from a '76 to swap over on my '72, all the brake components are bolted up, have all the brake lines in place, but having trouble with booster and master. '76 master won't bolt up to '72 booster because bolt pattern was changed. The booster from the '76 is about twice as large as the stock one, so unless I move the slave cylinder a few inches, it's not going to fit, which I am trying not to do if needed. I read one guy on here used the front plate of a booster from a '74 Celica with the stock backing plate, but would the power be much of a difference? Also, that the '81+ 2WD boosters are smaller, but small enough to fit without needing to move anything else? Thanks for anyone who can help me out here.
