That's okay I seem to have one heck of a time's on a weekly basis most times!
Since it's a used set I can try my best to match up the old wear pattern. I originally added a pinion shim and it made the gears bind, but it was a thick one so I'll start off with the thinnest. I'd be working towards more of a center pattern then?
About the set up bearing yes I read about that along the way and made both of the old pinion bearings interference fit where I can pop em' off by hand. Thanks for looking out.
