Thanks guys, I think the early 4X4 SM465 had the 10 spline and then changed to the 32 spline on the later models. 2 wheel drives had the 35 spline. I was able to get the bell housing that came with the transmission. I will just need to find a part number for a 283 flywheel.
All SM420, SM 465 & G.M. versions of NVG4500 have 10 spline input shafts, are you sure the 32 & 35 splines aren't the output shaft?
