I sorta dropped off this thread because I couldnt get a good look @ the tooth condition of your old R&P to give a definite yay or nay on those two parts. Lets put it this way, if the tooth condition is OK and the 'spigot' of the pinion which runs in the roller brg has not been overheated or worn while without lube and the Ring Gear & Carrier spin Freely & Quietly after you have removed the pinion assy, then you may get away with just pinion brgs,crush sleeve & seals. IF you can do that then you should be able to reuse the existing shim as MOST times doing a rebuild in this manner does not require a change in pinion depth setting. Good Luck.
