Really good progress in the last week or two. Steering is done. I reused the RX-8 column. The adjustable height mechanism was removed and the mounting bracket welded directly to the column. The steering shaft itself needed to be lengthened by 11". I was able to use the RX-8 switch gear so blinkers and lights will be on the column.

Even more exciting is the engine and trans are mocked up in the car. I've got the left side motor mount done. Bent up some .09" steel and used a Land Rover Defender rubber engine mount. The engine sits 12" further behind the front wheels than original which was just behind the wheel centerline. Is it able to be considered a mid-engine car at this point? Wish I had taken a top done picture so you can see how far back it sits.

Started fitting the rear body work so I know how/where to brace everything. I had to cut the piece down the center to make it ~2" wider. Also had to slit the upper corners to allow the sides to move out. As molded it had a pretty good tow in at the front of the body work.

Added in a crash bar to the back. I was pretty worried what was going to happen in a rear end collision in this thing. Especially with the fuel tank in the rear. I still need to add some diagonal braces going for/aft going to the bottom of the roll bar rear legs. It made a nice spot to attach and re-enforce the upper rear rail too.

That crash bar is a nice idea. I guess a person would have to be careful to leave enough room to get a gas tank in and out, but other than that, it is a good safety feature.

Cheers,

Removable bars would give good axes and rigidity .
At any rate I'll be adding one of those to my build .
Cheers for the good idea

Some more pictures of the crash bar with the additional bracing and got my pedals mounted. You can see in the pictures the bracing for the lower part of the rear body work. It unbolts to allow removal of the rear body work. Drivers seat is bolted in to but it's nothing exciting to look at. Will be working on mounting my radiator(from a 1984 RX-7) and oil cooler this weekend.

As far as getting the fuel tank in and out it will be super easy. My tank is a good 6" short of the crash bar. I originally had a larger one but wanted some buffer in a rear impact before it got hit. It's still 10 gallons so should be good for about 180-200 miles

Oil cooler and radiator are pretty much done. Just need to weld some posts to the bottom of the radiator to engage the lower mounts I made. Both radiator and oil cooler are from an 84-85 RX-7. Radiator I had to trim off the lower mounting tabs and and bend it in to clear the steering shaft. The lower mounts will be welded on pins that mate into Dorman 926-280 radiator mounts-

I started mocking up the header. I'm lucky that a company called Icengine works is just up the street and they're friends of the shop. They make a really cool kit that makes designing headers way easier. It's a bunch of snap together parts. http://www.icengineworks.com/

Here's the latest batch of progress pictures-

Rear body is all bolted up. Made a bunch of little brackets and used about twenty riv-nuts to hold it all together. Seems very solid. Still need to glass the two halves of the rear piece back together.
