1986 Convertible Quarter Windows

I posted in the classified looking for parts for this also but thought I'd throw this out in general.
I've been looking for parts for my convertible power quarter windows to no avail. They are very loose and need bushings and all that. But I looked at the regulators, and some of the pivot points are extremely worn out. Anyone have ideas on how to fix them?
I'll try to get a pic up of where I'm having an issue.
Thanks
Donnie
