Pinion Gear Step Machining

[Rowdy]

Last week a friend brought over a repop 3.54 ring and pinion gear set he bought about 8 years ago. Seems his is one of the sets from that run that the front bearing area on the pinion gear was not machined for a slip fit so setting the preload will be near impossible to set. Who have most people sent these to have them properly machined? Any help or contact info would be GREAT. He has had them long enough that the parts house will not take them back or offer any help. Rod
