The box is butter smooth right now, but I have no way of knowing if Roger used brass synchros or bushings, so I'm going to stick with a GL4 oil.

Hello Mike; I would suggest with a great deal of confidence, that if you spoke with RBT & referenced Roger's name along with the serial number of your ZF, that chances are very likely that RBT has the invoice & parts list of Rodger's order that would determine what type of syncros were ordered/installed.
