Has anyone replaced the nylon rollers on their window regulators? I'm not talking about the commonly seen ones that suits the glass, but the type originally riveted to the regulator arms. It looks like Dorman may make a set, hard to tell if correct and every seller uses the stock photos that I never trust, and the vague copy and paste description. Some are possibly just the nylon roller, described as plastic, others include the ball stud and require riveting in place, probably.
