are you looking for new or used patch panels? you would have to relead the leaded joint in the pillar at the base where it meets quarter panel. plus there is bracing in the interior and in the trunk in that area going to the wheel house that contains the torsion bar springs for the trunk lid. you need to really get a good look inside and out. looks like rust from a vinyl top, best if you strip the whole top of the car to make sure you know what you actually need
looks like it could be repaired with regular sheet stock or a panel cut from a parts car roof or a hood or trunk lid.
could also be repaired with lead.
