1969 Dart GT convertible top of fender trim.
Several years ago I purchased a bunch of sheet metal for my 68 Dart convertible from AMD, and had them ship it to me in Virginia. I don't remember the cost of shipping, but I don't think it was so much that I would have considered driving that far to pick it up. But you may be far enough south in Virginia to make it worth the effort. I'm in northern Virginia near Winchester.
Two suggestions. First, I would check with AMD first to verify they have what you need in stock at their warehouse if you decide to go there. But if you are going to Chrysler Carlisle, I would find out if you could order now and pick up the sheet metal at Carlisle. And if not through AMD at Carlisle, perhaps Stephens Performance as they always bring AMD sheet metal to Carlisle.
Be aware that the quarter panels are typically "somewhat" wrapped in cardboard (but not boxed). They won't stack neatly on a trailer and the cardboard will be susceptible to wind and rain on an open trailer. Floor pans and other structural pieces are typically loose. When multiple pieces are ordered for delivery, they are typically palletized together and covered with a cardboard "tent". That works well for an enclosed common carrier's boxed truck. They would drop the pallet at the end of your driveway. But, if you're picking them up, you'll need to figure out how to haul all the various shaped pieces on an open trailer and secure them without damaging them. Quarter panels are quite fragile until they are installed on the car. To me, thats another reason to have them shipped.
