Wilwood Question

You just answered your question.

73 and up will be 1.5 + wider.

All the drop spindles are designed after the 73 up setup so you use large ball joint 73 up upper A arms/aftermarket tube arms and that combination sets you out to far. The lowers were the same for all the a bodies. Change was to the spindle in 73.

And if your not dropping your car like mine then there is no need for a dropped spindle. You can lower your car a bit by adjusting your torsion bars.
