do you know where to get the rubber, for the rear track bar? i looked for a long time last night, an cant find them. an the other question, is, the one there right now is non adjustable. with a 4to5 inch lift. does it need an adjustable,front an back bar, if the tires are the same space from each outside spring? I been rolling out alot of questions on this forum, right now, cause i got a couple weeks free to just work on this jeep
