guys there are NOS sets on e bay all the time...I think I have two sets rat holed they go for about 25 bucks usually unless two guys need them right now...
confused how much air you guys are using...I always put in about 10/20#'s and they would raise at least 2/3 inches and were way stiff more like 8/10# for driving..If I gave them more than 20 they went like full tilt up...
your stuff sounds like there all done
