Rear Quarters Availabilty?

Is Laysons the only company that sell the rear quarters for a 65 Barracuda? I would like to stay metal if at all possible.

I started sanding the rear drivers side quarter and I found more "sculpting". It appears almost the entire wheel has been sculpted and a good portion directly in front. I already know behind the wheel well is a fiberglass patch so there is not much of it left at this point.
