There are a couple of common ways to set pinions. One is a crush collar that collapses at a certain torque the other is setting up a matched set of shims as spacers. I'm thinking clean it, torque it up and at least try it.

That's exactly what we did.
Thanks, John

The pinion nut holds the pinion gear where it's supposed to be, front to back, and against the ring gear. If you have no pinion nut, then nothing is holding the gear lash to spec.
You can't set up a rear with no pinion nut. If the rear WAS set up, then why would the pinion nut be loose from the get go? Doesn't make sense.

CWI or Currie.
bobbys Bob the only 2 places I know of are CWI which sells a complete rear flange to flange. The other One is Currie, They sell 9" housings with what every mounting system you are looking for. I did have a 3rd idea, install a Franklin Quick change rear like the dirttrackers. You have a 9" gears and an adjustable gearing in the car that can be done in 10 minutes. If you search this forum and look for 2000NJR or NJ2000R He did a franklin in his ERA cobra. He said not that hard, the only thing was that the ERA rear is in a support cradle and you have to drop the gas tank to get to the rear cover. Other disc brakes was another option. Something to think about. There is nothing wrong with a Jag rear if you beef it up with some better parts. Jag rear is good for 450HP. With a 30 spline kit you go to 600HP. Add a support cover for the rear to stop cap walking of the carrier. I have done this to my jag rear. Rick L.
