What to price a 1970 Super Bird at my friend is getting in a multi car trade

is there any paperwork with it? window sticker, fender tag, BC sheet, is the 6-pack in tact? all number matching - eng, trans, body? date coded correct when valuing cars like this - stuff matters.

need many pictures over, under, inside. While it makes me groan to say this Maybe consider having a professional look it over.
