So something i've wondered about forever but can't ever find good info on. 1981 was the only year for 81+ trucks where you could get green interior. It seems to be pretty rare except for in some Custom Deluxe or base Sierras. Does anyone have pics of a factory 1981 Green interior Sierra Classic, Silverado, Cheyenne, or Sierra Grande? Better yet, any Suburbans or K5s? I've never seen one of those either.
