I am following a thread on another forum. The poster says neither him nor the shop can get the called for seals into the holes for the shift rails. They are claiming a .050” difference between the size of the seal and the size of the hole. He has tried different seals from different vendors with the same results. I measured mine and the difference was around .016” for the SKF seal I bought to replace the Crown seal I ruined. I don’t think it would be possible to install a seal into a hole that is .050” smaller than the seal. Does anyone here have knowledge of front caps with different sized shift rail holes?
