Started a hydroboost conversion, wasn’t really sure we were going to do this but after giving it some thought it made sense. GM went to this system with the brakes we now have and I don't want any pedal pressure issues later, the donor truck stopped on a dime! Jim (JJorgensen52) did this conversion on one of our main inspiration trucks and he made it look easy
