There is a brass bushing in the rear support.
Originally the support and bushing would have been replaced as one unit.
The OD of the bushing is a standard size(don't remember the size right off). I have bought bushings from a bearing house that fit the OD and have a smaller ID than original. I then turn the yoke down to fit the new bushing ID.
If your yoke is not to bad the replacement bushing can be bored out to fit the yoke.
