That's what I was thinking. FREE. You'd be better off finding stock XJ leafs (since alot of Jeeper's lift their Jeeps). They are more ideal too. Same spring rate, width, etc. Keep your eye out for guy with lifted Xj's. Say hi to a guy at a stop light, join a local Jeep club, goto a car show or truck show.
Bottom line, be patient. A junk yard is a business and needs to charge. A guy on the street just wants them out of his garage.
I'd pay less for s-10's and more for stock XJ leafs.
