If anyone has any photos of a properly installed heavy-duty window regulator, please e-mail me a copy! I know of no installation directions in existence. My problem is that the regulator could not be made to bolt up properly with the supplied brackets. Since I'm not the only one with this problem, I'm beginning to think that ALL heavy-duty window regulators are like this. My theory is that the heavy-duty ones were designed to fit early VIN cars but can not be made to bolt up the same way to later VIN cars. Since my car came from the previous owner with one of these already installed, I assumed that it was an OEM regulator since it worked so poorly. If you already have installed heavy-duty regulators, read the following and tell me if you have any of the symptoms that I just corrected: The window now moves effortlessly with no slowing down as it opens or speeding up as it closes. There is now no binding or torquing of the tube. It now no longer scrapes my window tint film or puts pressure on the door skin. The end of the lead-spring now no longer runs past the gear when the window is rolled all the way up. I now no longer need an extension bracket like a few other people have used as a fix to stop the ratcheting sound at the top of travel. The glass now no longer disappears too deep into the door where it tended to scrape the window fuzz off. And now the window stays on track. (Imagine that.) Just how much can go wrong with a window regulator anyway? I started by making a small slip-on bracket for the very top of the tube and attached this to the inside of the door with a screw and spacing it out with washers. (It attaches in such a way that it does not block the slot in the tube.) With the window rolled up, I determined the proper location for the top of the tube & the new slip-on bracket. Then with the window rolled down that put the bottom of the tube in the correct alignment. Since the tube could slide through the slip-on bracket at the top, I was able to determine the optimum height of the regulator in the door. This was the perfect orientation of the tube to effortlessly operate the window, but the shape of the tube made it impossible to not interfere with the door skin. So I had to bend the tube slightly. Then the dog-ear tab welded on the regulator tube didn't even come close to reaching anything that I could bolt it to. In addition, the bracket for the grab handle support was now chronically in the way, so I drilled the spot-welds out and removed the back part of it. (I hated that thing anyway as I always had to pry it through the opening.) Now with it gone, I had plenty of room to make new brackets. With what was left of the door handle bracket, there was a convenient unused 6M screw hole, so I used this as an attachment point. I ended up making 4 new brackets out of 1/8"x3/4" aluminum. This is plenty strong and lighter than the combined weight of the steel that it replaced. I'll post pictures when I get a chance. If anyone has any similar experiences, please confess. Thanks.
