I hope that Stock 49 has done/ will consider the conversion. I remember in 1976 when in mechanics school we did the front brakes on a 56 Chevy that one of the students had. When I pulled out the wheel bearings I was shocked to see a ball Bering unit instead of the tapered roller bearings that I was used to. That was the only car that I ever seen those types of bearings on. Everything else that I worked on was too new. Jay
