On the left is a bucked style of rivet, which is set with a rivet squeezer; it actually deforms into countersunk a countersunk hole on the back of the work to provide a flush finish on both sides.
These are aircraft rivets, used in applications where drag reduction is paramount, so no protrusions can be allowed.
Safe to say these pieces are securely fastened. I did a few more just to do it, and they all worked very well. I'm convinced.
That's for next weekend, though.

Here's the fuel tank in the car. It sits back flush to the vertical place formed by some frame members. It's a bit hard to see from this picture, but there are a couple of things that protrude through that plane, and therefore through the firewall skin I am putting there - the filler neck and the vent fitting.
Tubes from both of these will go up and outboard (left in this picture) to the fuel filler on the fender.
Here, I have three panels mocked up to form the lower and middle sections. There's also going to be a vertical upper section lying tight against the upper aft firewall skin (this gets important later), and a small lower center section to cover most of the gap (but leaving a space for shift cables and wiring to pass through).

Next up is to get the tank actually bolted to the chassis. It does have mounting ears (you can see one of them in the previous picture), so I will drill through those and get some bolts into the frame and the floor. I am waiting on some rubber tape, though. Should show up today.

Previously, in the build...
I'm using a third-party fuel tank in the car. This means I can't use the firewall that shipped with the kit, so I have to make my own.
I've elected to make it by riveting together flat panels with aluminum angles. So this is an angle here - nice and square. But I don't want it square, I want to open it up a bit, to about 112 degrees, to match the sloping front face of the fuel tank.

I also did a bunch of thinking and planning about the firewall at the rear of the cabin. I believe I will not be using the firewall sections provided with the kit, but I have not yet decided 100% what to replace them with. Options include .063" aluminum, .125" aluminum, mild steel, and carbon steel; and welded or riveted construction.

Note the spiffy adjustable forward lateral links - those should help dial in the rear alignment.
