Clutch Alignment Tool

I am having a difficult time procuring the Miller 10018a clutch alignment tool. So I figured I could use the Ram 03-013 clutch algnment tool that GM uses for their manual vehicles. I understand that the Challenger pilot bushing is a different size than the GM bushing. I can have the nose of the Ram tool modified to fit the Challenger bushing. Are the splines on the tool are long enough for this to work?
