JK parts for an XJ?

My friend just ordered a 5" lift kit w/ everything (uppers/lowers/track bar/springs/brake lines...) Is there anything I could use for my 91 XJ on 32's 3" lift?

assuming you mean he ordered a kit for his jk and you want to know if you can use his old parts for your 91 xj?

i don't know the answer to the question, but your question lacks the depth I'd need so that I can answer it.

There isn't really much you can use for your xj because all the brake lines are different, all the shock are different and you can use the springs for sure...so there's not much to salvage there.
