the SPID label sticker in glovebox or on inner fender underhood is the only way to get what all options came on the truck
yuo cant find them out with a chevy vin, chevy didnt save this stuff,
but i think you can in canada,
the vin will only tell you year and engine and model/series and plant and such
not any options ordered/installed
youre SOL on that one, unless you have the SPID sticker still intact on the truck or find the buildsheet, almost always underneath springs of the seat, i have found many build sheets in gm trucks 73-up here.,
good luck
