Review on Dorman 741 721 Toyota Driver Regulator by Will Kern

I paid about $40 more for this part than the others with bad reviews. During installation the motor assembly had some play and had to be adjusted about 5 times to keep the window on track. Worked about 10 times and then got out of the rut. In short, this product needs stronger metal on the threads. I have 2 who are naked and afraid to pull the other up. I'll try to put nuts on the back as I can't replace them or I won't have a window in my car until a new one comes along. Unsatisfied. I would contact the seller directly for advice, or that seems to be the only way to contact him.
