". . . is there an american OR canadian company that stamps fenders,hoods what have you,as opposed to buying offshore?
The dynacorn parts look similar to parts from USA companies. The EDP-coated panels look very similar to some excellent panels I have used this past year (made in China and sold by USA reproduction parts vendors).
Jim Carter sells a variety of patch panels made in the USA (some better than offshore panels, some are so-so). He sells the excellent panel-body-specific repair panels made by Ray Stanley in MA/USA.
