Rusty Dodge, yes, the upper quarters were taken from a donor car. As for the lower quarter pricing, I haven't received my receipt yet, so I really don't know how much it was. I think it would be safe to say expect to pay between $250-$500, depending on what the going rate for your local shop is. Mine was at a neighbor/friend discount, so I would say I paid close to $350 for the welding and fabrication of the lower quarter. Reproduction quarters have their share of work needed to get them to fit up nicely. Originally, he had expected it to take 10 hours @$25 to weld in the quarter, but that didn't happen...
Hope this sort of gives you an idea.
