In a different thread, I explained how while I was trying to fix the attachment point at the bottom of my 56 Dodge's right front fender, I had snapped off the bolt and then while trying to fix that situation, I managed to dislodge the OE captured nut (which had been welded to the bottom of the fire wall bulkhead). That meant that I had to figure out how to attach the bottom of the fender to the firewall again.

This is the hole that I had to fill:



Several suggestions were offered (thank for those guys). I opted to try a "Jack Nut" which I recently found out is also called a "Hanson Rivet".

REFERENCE: http://www.forwardlook.net/forums/forums/thread-view.asp?tid=76246

My neighbour gave me a 1/4 x 20 Jack Nut and an installation tool (a long nut). I bought a 1/4-20 x 2.5" bolt to install the jack nut. I slipped a washer under the tab of the fender before I installed the the Jack Nut (to make sure that the Jack Nut didn't pull through that square hole) and proceeded to install the Jack Nut. Very simple. Felt for the "wings" of the Jack Nut through my "Access Hole" (which I created with a drill) but I could not feel them.

I installed a 1/4 x 20 stainless steel bolt and fender washer to hold the bottom of fender to the body and quit for the day (yesterday).

Today I took some photos of the installation. I still cannot see the "wings" of the Jack Nut but it seems to be holding regardless. I sprayed the cavity yesterday with Rust Converter. Today I spritzed up some Zero Rust paint. Tomorrow I am going to patch the access hole with sheet steel and then spray the entire rocker interior with cavity wax. Then I will do some painting of the patch and the exterior of the bottom of the rocker.

Not pretty but at least the rust will be slowed and the fender will be attached better.

Photos from today:

I strongly recommend you put lots of anti-seize on that bolt if you think it will ever need to be removed. Rivnuts don't work well in areas prone to corrosion as the bolt will seize and the rivnut will spin.
This is from many years of experience.

Like this OE one (that seized and snapped when I tried to remove it)? (Thanks for the suggestion)
