Lower Wheelhouse Replacement Part, Is it meant to be single layer, or double? Options

[Gudhjem]

I’m working on repairing the area below the Hell Hole – basically the bottom of the passenger long around and behind the jack post.

My plan is to preserve the double-wall original aspect, so I’ve been taking pains weld new metal onto the inner C-shaped long pieces before I repair the outer pieces that sit over them. TIG welding on slightly pitted 20ga is challenging, but I’m managing. I’d rather not go the single-wall replacement route that the RD/AA inner long piece for the engine compartment is designed to do (the one with the corrugated ribbing that shows after install).

As part of this, I need to replace the metal around the jackpost on the inner wall. I’d like to be able to use this piece from RD:



Can anyone tell me if the RD piece is meant to go inside of the outer long (like the original configuration) or if this is meant to be a single-layer piece, with nothing over it? I'm guessing it's meant to be single, since I think I see a flange on it, and the inner "C" channel pieces don't have that. I’ll have to do some pretty tough fabricating to get the jack post hole right...

It's meant to be 2-ply.



The smaller part with the round hole in the jackpost area goes inside (behind) the larger part.

Yes! That smaller part in the bottom of your pic is exactly what I'm looking for. But I don't see that on the RD site.

Did you get it elsewhere?

EDIT: I talked to RD. The part I ordered is apparently BOTH parts, with the smaller part already spot welded inside the larger part. Although I'll have to drill out the spot welds, nice to know it's all there. Thanks for the pic.
