I converted my G20 to power windows, so I don't need these anymore. They came from a 1985 G20, but I believe they fit almost all G-vans from the early 80's through 1995. I think the older ones are different, but I'm unsure what the year cut-off is.
These worked perfect when removed, includes cranks.
A member had expressed interest in these months ago, but they haven't seen my PMs for the last several weeks, so these are now for sale. I'd like to get $75 shipped to the lower 48 USA.
