T56 main shaft part number I am trying to find a gm part number for the 32-spline main shaft used in the 2006-MM6 t56. The part number im finding is P/N 12454996 but i cant tell is thats right because of the poor descriptions. Also is it the same shaft used in the MZ6?

TUFP4203 is the tremec p/n
89060071 is the GM p/n
12454996 is the MZ6 (and other non-Z06 MM6, M12 corvettes) mainshaft and is 27spline.
32-spline was in the non-Corvette style SSR T56.
