Early A Body aftermarket sheet metal

I got my rear floorpans from Auto Body Specialties. They were heavy gage metal and fit good. I have the outer driver's quarter patch panel from Layson's and it's very high quality too. All of the mock up I have done with it so far, looks like it is very high quality as well. Classic Industries also carries them as well. I THINK all three companies get their panels from the same place. Maybe @Rick@Laysons can fill us in.
