Good value compared to OEM, but required some modification for my 2000 E46 (323i)

Part: Front Right Window Regulator
At a fraction of the cost of OEM, this appears to be a solid replacement. I did run into a couple problems during install that I resolved with simple modification. No installation instructions are provided, but it's easy to find videos on the web that outline the replacement steps.
As this item does not include the window motor, you must either transplant the motor from your old Window Regulator assembly or provide other. I found that the mounts did not line up with the holes on my E46 window motor. The motor hits a stop before it can be rotated fully under mounts(see pic). Rather than modifying my OEM window motor, I chose to enlarge the mount holes on the new regulator using a Dremel and small stone grinding tip. I taped over the gearbox to prevent intrusion of metal filings(see pic). With that, I was able to secure the motor on regulator mounts(see pic).
It was also noticed that the outer regulator support arm(without gearbox) had a sharp burr along the outer edge(see pic). Fearing premature wear of the window glide, I deburred the edge with some sandpaper and regreased.
The cables on old BMW regulator rails run across greased pads. This regulator does not have pads nor comes well-greased(see pic). Before installation, I applied generous grease to all cable runs. I used general purpose lithium as that was all I had on hand.
Tested operation several times immediately after regulator install and again after door panel and remaining parts reinstalled. Regulator runs well; time will tell if it lasts. Will update review if any problems arise.
