B Body window sliders

Anyone know where I can get replacement parts for those little plastic "sliders" that are part of the window regulator on a 71 B-Body? They may come with the metal stud part too. I've busted one of mine and the window won't work.
Thanks

are you taliking about the plastic sliders that pass through the window and ride in the side channel?

Thanks for the reply. What I'm talking about athe square plastic pieces that ride inside the channel. These are not the ones that go through the glass. They have a round metal part that attaches to the plastic and a shaft that is swedged to the window regulator arms. I thing that are as many as four of these per window. I've attached a picture but the quality isn't very good.

Try R/T Specialties, 570-388-1082. He carries all those clips and hardware.

Thanks. I'll give em a call
