It was inevitable. I "borrowed" a 7.5" rear with mini-spool from a buddy to test my theory about a defective differential. On the first pass at the division 1 bracket finals the drivers side tire and wheel left the body to pursue a solo career thus ending my season in disgrace. He swore it had 28 spline axles in it but the autopsy proved otherwise. At least it happened right at the line instead of at the 2-3 shift.
