Thanks for the quick responses and sorry for my late reply. Take a crisis and add a holiday and you lose two weeks time really fast.
I also need to apologize for my first post here having a couple of errors. Not only am I trying to revive my FS5W60L, but I am also helping a friend rebuild his FS5W60A that seized the input shaft bearing. So too many part numbers floating around my in my head. The part numbers given to me by the parts man were the same as datzen mike posted with the exception of the letter in the second set which was H for the 60L and N for the 63A. But when he printed the numbers out for me it just listed the one number with the H. This bring s us to my second error which is that while I was sure I needed the 1st/rev synchronizer hub it turns out that I need the 2nd/3rd synchronizer hub. so the same question applies, are these hubs shared between the 60L and the 63A transmissions.
Mike, sorry for wasting your time with the wrong info.
Eric if you think you have the 2nd/3rd Synchronizer hub I will PM you to set something up.
To follow up on having the main shaft machined. The one shop I talked to said that since the shaft was most likely hardened is could cost up to $500 to have the work done. So I will just keep looking.
