[ERASER5]

I read the "except 5 lug", so that is a maybe. You must measure the 71 rotor. The rotor must be 1.25" wide. That is considered "heavy duty" and that is the size of all the aftermarket 6 lug rotors. The spindle length is the deal here. The 1" rotor version fits a shorter spindle.

I did tons of research before I converted my 70 to 6 lug disc. Bottom line, 6 lug discs are 1.25" wide and must be installed on an HD spindle. Grab you ruler and measure.
