I started by installing medical grade construction sound deadening material from floor to ceiling and covered that with carpet pad. Since the rear was tubbed to allow the car to sit lower, the original rear seat was unusable. So I made the rear seat and center console. The front seats and swivel mounts came from a boat supply shop. I upholstered everything in grey automotive velvet with wine welt and buttons. All mirror tiles are hand cut by me. The floor is grey carpet inserts with grey velvet wrinkles surrounding the inserts and button tuck floor mats to cover the carpet for show.
