Good advice as usual from Bob and fellow CC members.

I used PEM nuts and allen head / button head stainless button screws for my transmission tunnel, it turned out great.

Below is link to a web page with a chart, they come in #4, #6, #8 and #10. The chart has recommended sheet thickness and hole size needed.

PEM Self-Clinching Nuts, Type SP - Unified On S.W. Anderson
I had a chance to check this out and it looks like the PEM nuts might be a good option. PEM claims they hold tighter and are inherently flush on the mounting surface. But it appears they could be a bit more difficult to install for this application because you would need to apply the punch on the bottom of the panel, with the "anvil" on the top. Was it difficult for you to do this, and are you glad you went with the PEM nuts vs the Rivnuts? Thanks again.
