Not sure on the gauge specifically, but I am finding that depending on the panel and who produced it, its not worth the money for replacement parts. Nothing I have purchased from LMC has fit right unfortunately. I save them for non-sheet metal stuff. The panel I am looking at currently is the left side full cowl replacement, some offer 19 gauge, and some are offering a 20 gauge replacement steel. Purchase the highest quality stuff you can. Fender-wise, I would search for a nice pair of originals.
