booster

NMNA https://www.bmw2002faq.com/forums/topic/193675-tii-brake-booster-rebuilt/

To what length should the pedal to booster push rod be for the T51 booster/3.0 master cylinder be adjusted. Is this different than the factory specification for a 71 2800cs? Are there other things that should be adjusted to insure the booster works correctly?

I have an unknown brake booster in a 2800cs that was converted to triple sidedraft Webers and then to dual downdraft Webers. The booster is marked ATE T 51 and has a ATE part number label with the number 3 6152 0701.4 . Is this at tii booster? What is the outside diameter of a tii booster...
