I hear you can re-install old parts once you've uninstalled them.....
Just rumor though, can't hold me liable if it doesn't pan out :P.
Isn't the "fix" to use GM Syncomesh fluid after the new syncro's are installed? If that's the case you could just switch fluid now and avoid ever having to deal with the problem - then you could legitimatly get your short throw and not worry about it

I'm experiencing the problem now, unfortunatly.... I'm going to try switching fluids to see if it makes any difference.
