741 - crush sleeve and shims?

Thanks guys, just as I thought. I know Dr Diff is pretty good usually, although on the two occasions where I emailed both these guys to confirm, with what I thought were emails worthy of a good reply, both were not at all helpful (no helpful explanation, just a link) so that's why I came here on this forum. I thought at least Cass would have been more helpful as I explained my situation and especially as I recently bought a new SG unit from him. Oh well.

Thanks Helllrats, that is exactly the plan of action I had in mind, even with my limited knowledge of these pumpkins. But can you tell me one thing not answered, is there only one type of shim in the 741? And does it only go in one position on the pinion? I suppose I should get off my A and look at the Dodge factory service manual, the info should be in there.

Thanks.
