selling it? I would ask about $2,000 for the entire interior, seriously. to acumulate all of those parts one would be looking at paying about that much in parts and shipping over time if they were to try and make that conversion.
Fronts alone: $400.00 or best in great shape.
Rears alone: $300.00 or best in great shape
Rear inbetween seat console storage unit: $60.00 in good condition.
Both fronts and rears and nothing else, $650.00 firm.
Door panels and rear panels with inserts: $250.00 set of all 4 great shape.
Rear 6x9 sub console: $90.00 or best (someone will pay everyone wants it)
Center console: $100.00 from radio to rear complete.
Rear seatbelts: $50.00 for the set or best.
Rest of plastic including dash back: $200.00 or best
all those prices are my estimates on value. I dont know the current going rates nor do have any of what you have for sale. I am just saying what I would price the stuff at given it's all in good to great condition. Shipping to be added onto the parts which are being shipped on top of those rates.
Again, this is just my opinion on the values. Others may vary. good luck and to bad i went broke rebuilding my motor or i would buy your interior.
