Mike, I am not sure but I do believe the splines are different from a gasser A518 to one for a diesel.



Thanks for reminding me. I was going to address this in my first post. The spline counts are as follows:

23 Spline
Gas small/big block V8s
Diesel automatics
V10 automatics

29 Spline
Diesel manuals
V10 manuals

I can't remember if the internals are different from gas to diesel, though.
