Being brief, I have an all original 1966 pontiac Parisienne (Canadian specs with shipping docs) and I really need to change the Brake Booster/ Master Cylinder out. I can't find one on line anywhere so now I'm trying to see if anyone knows (absolutely without a doubt) what car has the exact same fit??? someone told me a Catalina then someone else said the Bonni.... So before I spend the money I would like to know for sure (year, model, etc....)... any true help out there??
