Search e30 m50 swap booster on this forum or google. I just measured an inch from the stock holes and drilled new holes. It doesn't look like the pin will fit in the pedal but it will. Use the stock booster unless you can afford to get an e21 or porsche 944 booster. Or just relocate it and use the booster out of a 540i
