Hey guys, i have a question about gm hydroboost units. I have about 5 of them in my garage and i was wondering if there is a way to run the numbers and get some info on them. Or, is there something i can look up vehicle info on? For example- GVW on a 1986 Chevy truck or something. Also, to get the master cylinder bore size, can i just mic it or is it a different measurement? Thank you for your time!
