They don't make such a shaft, all the replacement shafts are the same design. You would have to get an aftermarket upper a-arm that is adjustable, maybe AIM has them. If your slamming the front, thats one of the problems you run into. If it's stock, them take it to another mech. I just put a new front end on mine, shafts/arms/joints/ect.ect. The guy at the alinment shop had no problem setting me up.
