i cant help you out, but i can tell you i feel your frustration. When i bought my YJ, i didnt notice until i barely made it home that someone went "redgreen" allover the damn thing. But the biggest thing is they used duct tape to attach the upper steering arm, to the lower, because the slip joint wasnt long enough to attach. Took me about two days of hard hammering to lengthen the shaft.
If you really need a new shaft, sadly, very sadly, you may have to go to jeepstuff, and buy one. You may have to sell half your family, cause they will charge you up the ying yang for anything these days.
