Special "fall harvest" package??

[Primer69er]

today i saw a 1969 c-10 lwb with a very ugly color, it was dark green yellow 2-tone, (the yellow is where the white would be on a factory two-tone, roof and all) the guy told me it is a very rare package, it came from the factory that color, and they called it a fall harvest package. i cant find a damn thing about it anywhere, and i think the guy is FOS or at least was mis-informed.

the seat in his truck is the same as the seat in mine, is white vinal, with green pladd. (btw mine is in excelent shape) he said that the seat only comes in that model.

so is my seat worth some money, or is he full of it???
