There's not much of interior, body there is and there isn't. It kinda weird how the engineers put this together but it wasn't intended as an assembly manual. There are pages of paint codes, stripes and decals, seat assembly part numbers and so on.
If you or other members have a GM fbody 78-87 there's info on those cars in books. Just PM me on those cars, this is a gbody forum.
