Scott, Ive never done one the firebirds, but I have set up plenty in the heavy equipment world. You need to have a dial indicator , inch pound torque wrench and a mic. You need an asortment of shims and blueing or white grease works to read the tooth pattern. Oh you need a press for installing the pinion bearings on and off so you can add or remove the shims. My question is look at the end of the new pinion gear. Is there a number stamped on the end? Does the rear end use a crush sleeve on the pinion? Joe
