ComandoXJ96, go ahead and get the ones that XJmainia030 has, there's no way I can get to Tucson any time soon.
XJmainia030, thanks for your offer.
Alex,
You're welcome to come over and watch/help. When depends on when I get a set of XJ leafs - I'll probably call AMC4x4 tomorrow, I'm sure they have something. If that's the case I may try for this weekend.
I have the parts for a 3.5-4.5 lift with RE parts up front, a set of bronco II springs in the back and a 1.5" shackle and a bushing kit I hope to mate to the stock XJ main leaf and shocks all around. Will that flex? Don't know, hope so. I think the flexibility depends on the donor pack - in theory more thinner layers would flex better than fewer thicker. Bronco II have more thinner leafs than, say, S10 springs but still have an arch. It's probably not much better than buying decent springs from someone but chalk it up to "that sounds doable."
