Yes, I have replaced three of the four regulators on my 01, all with the same broken plastic piece that allowed the cable to slip out and I have bought whole regulators from the dealership for 300 bucks before finding out that someone devised a nifty fix with common hardware items (kind of a Why didn't I think of that moment.) It may be on another forum where I saw the fix.
I haven't found any Dorman pieces that resemble just the plastic piece which is like a square block that rides up and down the guide track. It gets brittle over time, then cracks and that lets the cable pop out.
Another word to the wise. Hang on to the old regulator assembly. Luckily I did, because I had an actual motor failure and was able to use the motor from the saved part to repair the newer one.
