The one panel that comes to mind is the inner to outer cowl piece. There seems to be two types, ones that are stamped with round indents for the kick panel bumps and another welded with rectangle indents for the kick panel bumps. The welded one is terrible. The other looks more correct but have not used it. The kick panel inner piece is not bad but the full pieces from what I see are better. I used the partial piece and the bottom curve is wrong and needed to be bent and something I noticed after as I had the doors off is they also need to be tweaked to line up with the door lines on the inside. The floors I used looked correct but when I used a half piece for the drivers side the bead rolled bumps don’t line up with the rest of the bumps across the floor, but look okay. My truck is a 1954 GMC Canadian model and that may be why as it could be a little different than a US truck.
