k so i may finally have all the parts to get the truck back together this week now my question is the. bearing spun on the pinion destroying the shim that was on it. Is there an easy way to tell what shim i need to shim the pinion with? i can't go off the factory one since its gone! I've got the back lash setup in my brain real good just need to know how to get the pinion shimmed correctly. thanks!
