hey Ted...I have the AF/X gears in the 9" for the 63 Dodge...they are 4.57's, spool, 35 spline axles...Strange set up..

the guy that set mine up said he angled the rear of the ring gear slightly to aide in gear climb for cooling ...Im putting mine on the street..

by the way, the NEW 499 that was built out of the old one has run today on the dyno!!...new block, Pistons(dished for 10-1 compression) for pump gas...had the wild roller cam reground to save some money ...sound totally awesome...also installed billet main caps and the old girdle...

north of 670hp stopped at 7200 and still climbing...that should make one awesome 2800lb street machine capable;e of running low 9's.....

sorry for intruding on your posting but I just had to tell ya....
