My last aftermarket input shaft didn't have the clearance issue and the bearing pressed on like a stock unit does. The latest 9310 input shaft has a .000 fit from my measurements so in theory the sleeve retainer will be just fine. Once it's all put together there is really nowhere for the input shaft to go if you think about it. On the other hand not indicating the bell housing will cause problems. To answer your question I am not sure at this point. That said I am going to run it and beat it like it owes me money. I can't really go back because we have out 833 gear sets face plated with Liberty stuff. Let us know how yours works. We are getting into floating on the pond and convertible season around here so my interest in cars wanes seasonally. We might have the red 4-speed Charger running this summer but I have pretty much given up hope lol. Good luck and happy shifting!
