I have a heavy duty regulator in the passenger door on my 82, #10270. > 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: If I remember correctly, the effectiveness of the motor/regulator is severely compromised if the 3 dog-leg mounts aren't bolted to their proper positions. Since the mounting hardware consists of 3 separate legs, stacked on top of each other on a mounting bolt (instead of a single, flush, statically mounted bracket like the stock regulator) you have to be careful how they're installed or you can 'twist' the regulator and cause all sorts of problems with alignment and operation. Perhaps the installer simply shoehorned it into place and bent the assembly in the process. I'm pretty sure that I'm remembering this correctly, but is has been about 2-3 years since I installed mine. If anybody has any corrections, please correct away! One thing that I do remember is that if the motor is properly installed, the regulator tube doesn't feel right when bolting the glass to it. On my car, the regulator tube was pushed against the outer door skin and had to be pulled away when bolting the glass to it. Nothing really lines up very well with the new regulators; that is my main complaint about them. You can't easily judge if it's mounted correctly simply by appearance. You're experience with the regulator sound pretty awful. But, besides a few cuts and scrapes, my regulator went in without any big problems and works like a champ. Good luck! -Luke #10270
