I got inner and outer lower door patch panels from Northern Cl***ic for my doors, unfortunately the company is no more... However, I vaguely recall some other vendor selling them.... Here's an old ad for the outers: https://www.ebay.com/itm/1751975967...=true&nordt=true&rt=nc&_trksid=p2047675.l2557 I don't see anything for the inners which would be the harder ones to make... IMHO
I see a sticker on the Ebay parts that says *****in Parts, Absolute Sheet Metal... I don't see the COE door panels on their website. Maybe a phone call is in order... https://absolutesheetmetal.com/
Here's a cab with what appears to be savable doors on your side of North America. https://www.facebook.com/groups/922...86107634764029/?sale_post_id=8686107634764029
Try this website. They seem to have a decent COE with nice doors and they advertise that they are parting it out http://www.rockymountainrelics.net/photos.php?photodir=47 Ford COE Fort Collins, Colorado (970) 686-2926 Email: tav8carsnparts@aol.com
Also, ask them if they will ship parts on a greyhound bus...it's much cheaper than other shipping methods They just put the parts in the cargo hole with the luggage.
Another FYI. There is no longer a Greyhound in Canada. They folded here in 2021. Very sp**** bus transport in this vast country.
