I found out a couple weeks ago my rear uprights I had purchased from a CAV would not work with my wheels. The radius rods mounts were 3" inside the rear wheel.:sad: So building rear uprights was back on the list. Went to pull a part years ago and purchased the drive shafts,stub shafts, hubs, bearing brackets off a 1989 Merkur Scorpio. So I have the bits to get this done. In a couple of lunch hours the register hole is complete in one upright center.
