The numbers on the one case are 5x8, 7x14. He left the other two at home. They are all 23 spline according to him. We figured out by some research they are all A833 trans. Also they all hhave the forward shifter mounts. One still has the shifter attached and looks to be original. If anyone is interested, Let me know and I'll give you his e-mail and/or phone #. He does have one listed on Ebay starting at $75.
