Well, no one else is going to finish this project, so it's up to me to finish it.
I built the transmission tunnel. The area around the driver feet and along the floor is made with 1/8 steel, the rest made out of fiberglass.
I used foam poster board from the dollar store to build it. I removed the paper, so it was just the foam, and then used aluminum duct tape to tie it together, then with spray adhesive, covered it with aluminum foil. So the polyester resin doesn't melt the foam.
Then laid up the fiberglass, 3 layers. Once dried, I use carb cleaner to melt the foam and removed the tape. It is nice to have the foil still there, but is isn't stuck on too well. I then painted the engine compartment and the interior in silver (the color the car will be). Now I can put all the front suspension and steering back in. I need to make up the SS brake lines next
and install the master cylinders and the pedal assembly.
