B-body convertible rear quarter window mechanism parts?

I'm trying to help a guy restore his 1970 Road Runner convertible rear quarter widow mechanisms, all of the track slide bushings etc. are worn and shot. Does anyone make reproduction parts for these?

mega parts carries a lot of repo window track parts
they were the only one that i found that had glass stops.
rt specialties also has some regulator slides
between the 2 they should have what you need.

Thank you!

You're probably OK with RT & Mega, but double check the appearance vs. the worn out parts just to be sure. Things get weird in the back on convertibles

Be careful of Mega. I got some for my Superbird and they were poor quality
