does the bodyman have something upon which to base what he thinks? I'd expect seat covers to be gray standard, like the pickup and panel, and some textured cloth with gray edges for deluxe [optional "fiber" cover], with frames same interior lighter gray .... and the dash top isn't actually "mat", it's the dark gray flattened enough to be "non-glare", same shade as the steering column, shifter, ebrake handle and floor .... you should track down some factory sales literature if you want to copy original
