Yeah, I left-out the axle upgrade due to a momentary lapse in judgement.
I did the 4.30's/31-spline Superiors/31-spline Eaton/T&A cover girdle at the same time, and would recommend a similar set-up for any Mach 1 owner who's going to frequent the track more than a couple of times per year.
(I always planned on some high-rpm launches, with slicks in my Mach's future this fall... )
GEARS AXLES AND POSI!!! nothing less then a 4.10
Chip!

Drag radial or slicks
