if you are asking me....I could never get a front steer rack to economically function properly with stock spindles....it might bolt up, but it was pretty much physically impossible to get the rack placed correctly.
This on is from Mancini's site. I called them. I guess they are modifying a Qa1 unit to Front Steer, using stock mopar spindles and some different Lower ball joints. Where do the lower ball joints come from is the question?? The sales person had no idea what part they were. Kind of messed up when they wear out and you need to replace them……
