Lower Front Fender Patch Panels for 1968 GMC

[canadaboy25]

Hey guys, I'm looking for some patch panels for my 1968 GMC 910 that has some major rust in both the lower front areas of the front fenders. I'm facing a somewhat strange problem as I can only find a patch panel for the right hand side and not the left. This site --> http://www.autometaldirect.com/tripl...nel-p-356.html has exactly what I need for the right side but doesn't even have a listing for the left side. I googled the name but for a LH version and didn't find a single one. Is there some specific reason that they don't sell left hand versions or am I just missing something?

Thanks
