These upper control arms are very nice. They are well made and the fit is perfect. The only issue I had was due to the location of the adjustments on these. I was forced to cut out a pretty significant portion of a spot welded body seam at the back of the inner fender. Also, some sort of instructions would have saved time and a little frustration as far as the adjustment, torque specs and maintenance recommendations. Installation is relatively straightforward and as I said previously, they fit perfectly. Ultimately, I got my rear alignment perfect. Thanks!
