The 4th speed synchronizer is part #103059 and the roll pin is part #103092.

Even though it doesn't act like a worn synchro, I may have it replaced anyway since I don't want to have the tranny torn apart twice if it is the problem. However I wasn't able to find the fourth gear synchro in the parts catalog. Is it still available? Also I'm having a problem with second gear that is most likely the roll pin (so I'm told) because sometimes it refuses to engage without grinding. Does anyone have the part number for this or is it just a standard pin found at an auto parts store? Thanks for all your help. If anyone has any advice it would be much appreciated. The car has only about 61,000 miles so I can't imagine anything else in the tranny should be too worn. payne proud owner of #2975 [Non-text portions of this message have been removed]
