Terp, you may already have it covered or may have another way, but my doors were aligned when I got the roller, and before I loosened the bolts on the hinges I drilled a couple of 1/16" alignment holes in each hinge, through the body and backing plate to ensure that I got it back to the same spot when the doors went back on, without any of the adjustment hassles and worries of chipping paint. Saved my butt when I had to pull the passenger door to fix a pinched wire for the windows a few weeks back....
