My Brother in law (17) blew out the rear in my Mom-in-law's XJ, and I'm more familiar with the CJ, YJ, TJ models.....also, how can I figure out the gear ratio without the tag (other than counting the front gears....nothing left of the rear lol). The tag is probably in the Fla swamps somewhere. Two door XJ's are more prevelant where I am, so I'm looking for parts, but she found a rear out of a four door. Now all we have to do is verify the gear ratio is the same.
