Hi guys .. new to trucks , have other tri fives .. My question is, I just purchased a 50 chevy pickup and lt has 5 bolt hubs and 5 bolt axles , the differential has U joints , with differant engine and tranny , I havent been able to have good weather enough to pull the wheels and drums, but from the rear they look like possibly original huc brakes .. Any Ideas on what could have been used to change to 5 bolt..thanks( I,m assuming original was 6 stud) thanks Fred
