TLDR: Either buy factory or the cheapest one you can find, all the aftermarkets are the same.
I installed this in my 2001 Suburban left rear door. I wrestled the old one out, got the new one in, and the top bolts didn't fit in my truck. The flange on the bolt is too big to go through the door to hang the unit as intended. They would work if you just bolted them through from the front side, but that is not how it's designed to install. Luckily the threads were the same and I swapped out my original hardware. My family and extended family has a few of this vintage suburban/tahoe and I have changed a few of these. This is the first time I've had this problem, however this is a minor inconvenience. I played with the clamps a couple of times just to make sure, but the operation is a bit suspect. It raises and lowers quickly, but at the very bottom you can here a cable binding noise in the unit and it's stops about a 1/16" from going all the way into the door. This wasn't enough of an inconvenience to me and the windows rarely get rolled down, so I'm going to roll the dice that it works, but it did not instill confidence in my choice of window regulator. Dorman or whatever the newest Chinese knock-off name is on Amazon or Rockauto, just buy the cheapest they are all the same. Unless you are going to pay money for a factory part, pick up the cheapest one you can find.
