@ Motorgeek--Keeping in mind I know nothing about this bottom end--that is, why it ended up in boxes--top end one box, bottom in another, I'm assuming you too would recommend tearing down the bottom end.  (If you can't tell, this is something I'd prefer to avoid, but am willing to tackle it)  Assuming that's the case, besides for looking for debris, are there any other things in general you'd inspect?  Finally, as for the boring and resleeving.  It seems you do that.  If you'd like to shoot me a price via PM, I'd be glad to have a look.  I prefer to use someone from the LT brotherhood rather than leave this to chance!  Thanks.
