How much would it cost to redo a cars interior by salvaging parts off other cars?

I have a 1964 impala and I need carpets, headliner, and a few other panels. I already own the door panels and seats so I’m good on that. Can I have a range? Ps these are used partsFirst, finding good used parts off a ’64 will be quite difficult. Items like carpet are not worth using used, same for headliners. New carpet and headliner, repop’s from a reputable supplier, say Year One, $500. For a car this old, the seat foams should be replaced. LEgendary has em. Figure $400 for the foams. Any other panels needed, watch swaps meets and ebay, figure $50 – $100 each.
