I doubt seriously that JC has an exclusive on parts made in the US. If you buy the same parts from another vendor they come from the same source.
Well many of the Cab part are and have been made in the US (Missouri & Iowa) for years by Jim Carters most of the other suppliers choose not to and order from a book of Asian made sheet metal parts. Only in the last couple of years did Jim start to carry the asian made sheet metal parts too, mainly by customer request.

Is correct in that his toe board, inner cowl panels, inner to outer cowl panels, outer cowl panels, and floorboard sections. Plus many other parts that most suppliers don’t carry.
Jim Carter has the same old books but has been in the business long be for asian companies were making truck parts.
I do agree with all of those that said they all (replacement panels ) will need some custom fitting.
