Broken Outside Door Handle Fix

[MHKitchen]

I replaced my driver's door handle carrier a while back, but my left rear door recently broke. I bought a Chinese replacement via partsgeek.com for $54, but it was impossible to get it to fit properly. I returned it and bought a BMW one from Stevens Creek BMW for $159 (OUCH!). However, I can't seem to get that one to fit either. The alignment on the rear doors is more critical than the fronts. The carrier doesn't seem to conform to the contour of the door, and thus its impossible to get the fake lock cover back in all the way. It has some tabs that must align when its pressed in all the way, that allows it to move forward toward the handle. Once its fully seated, then the hex screw will align. Otherwise, it won't. Have spent a couple hours now fighting it and trying to figure out how to solve this. It assembles perfectly off the door, but seems warped when its installed on the door? Anyone have any tricks for getting it aligned??
