Making a left into my neighborhood this afternoon, I heard and felt a loud pop under the front of the XJ. I pull into the driveway and have a look, and sure enough, the track bar bolt is sheared off at the threads on the frame end. Track bar is a 4"-6" TNT system, been installed for about 2 years or so. Should I be looking for a bolt similar to what came with the kit for a replacement (allen headed bolt), or would a simple Grade 8 from Lowes or someplace similar be sufficient? Also, anybody know what size bolt I should be looking for?
