It looks like i Might go with the Richmond Spool... It is profilied and Has more swiss cheese in it. That's always good! I have a strange 30 spline in both my 4.30 and 4.56 Pigs.. Never a problem.
The Moser Spool appears to be only for the 35 spline on the mopar 8 3/4" so I guess I will have to pass on that, but I will keep them in mind when It comes time for those gun drilled axles.
Thanks guys.
