That's a good question Eric. Since bucket seat covers were never available with Custom Cloth, all the recommended vinyl colors were available - but I think black buckets would still have been considered a non-standard order (or whatever the right term is for what would be an otherwise unallowable combo - unallowable without some form of special order (again, maybe not the right choice of words)). So, I think you could choose any color vinyl except black for the buckets in a dark olive Super (or any trim level for that matter) - or order black as a special order since black interior trim was not one of the options for any dark olive truck, regardless of trim level. But there's gotta be exceptions out there - or someone must've ordered black interior in a dark olive truck.
Here's the reference - note only the Super and all Dark Olive combos are grayed out for black interior trim. Also note the important note for dealers at the top - the word I was looking for was "recommended" - i.e. the only exterior color for which Chevrolet did not recommend a black interior was Dark Olive.
So, the question is - how did one go about getting an interior color that was not "recommended" by Chevrolet? Special Order?
