What is the overall diameter of an 80 series brake booster?

About 21 cm.

They fit straight into 60 and 75 series cruisers with a big difference in pedal effort. Get late (1990+) lux or 75 callipers and they get better again.

Fit straight into lux's too. I had to turn booster upside down (bolts are symmetrical) and mated straight up to brake pedal.

The only problem I had fitting an 80 series booster into a 75 is the shorter rod length. I had to use a union nut and a threaded rod to extend it to reach the brake pedal.
