If we cannot find a reproduction patch panel, can you buy a old fenders from ebay or swap meet and cut off those pieces and weld. Because at my skill level I can make a patch panel on the side where it bolts to running board but the opposite side of the whole fender is hard.

See the patch I couldnot find anywhere so I made one myself
