Does anyone know if anyone sells a replacement package shade for a 1981.
The return spring is sprung. Or does anyone know how to fix the spring?

Have you tried the salvage yards?
I use michagan corvette recyclers just because they are close to where i live.
paragon is another palce to look they have alot of items that no one else has, a little pricy but hey I guess you pay for what you want if no one else has it.
have you taken the shade out yet?
