question on clam doors
 

We're looking at getting a 64 Suburban how much is the basic price for a clam door setup if I'm wanting to swap it from the barn doors like decent shape you know not all rusted out with decent glass and know all the hardware and the lower Valance and not sure if I need to Upper Warren but if I do and also would it be possible to trade really nice barn doors with the the top Door Check slides no rest what would I be looking at price-wise with a trade like that to somebody thanks
