Well.....it finally happened
 

I went to roll the window up and heard a nice crunching sound. I can get it to go all the way up, but not all the way down. So I took the door panel off and found the white nylon wheel the cable is supposed to ride on missing. I found it rolling around in the door. So I put in an order to our awesome parts supplier Woody. I'll just leave it down for now so I can drop the top this weekend.

I feel your pain. I have replaced both sides with OEM. I tried a couple of aftermarket regulators and found them inferior. Returned them after they failed and went back to stock.
