I believe the upper cowl to lower cowl panel joint is recessed and leaded, so you need to melt the lead out to find the spot welds. I think I would modify the patch panel to fit instead of bending the original upper cowl.

That's the case if you got the full lower cowl panel patch. If you got the lower half of the lower cowl panel (doesn't go up to the hood), then just cut the original out and butt weld the new one to the remaining metal.
