Although I hope to never have a flat tire, I decided I should have a spare. I wanted a compact spare to take up less space and be lighter to lift, mounted in the normal place, but did not have any of the hardware.
I found a jack at the used auto parts store and mounted it with a rubber strap.
Then I had a local lathe shop make a cone out of a tractor tire and mounted it over a double threaded bolt which I could screw into the trunk wall. This gave me something to center and rest the tire on.
Then all I had to do was get a welder to make me an arch with a circle in the middle to go over the bolt, and points on both ends to go into two lug holes. He made this with a motorcycle shock absorber, a nut, and two bolts.
Once it was welded together, I ground it down, sanded it, and had it chromed. Here is the finished product, assembled both without a tire and with the tire in the entire trunk compartment. The bed box is the required emergancy triangle.
I made the mat out of the same cloth/rubber material I used for the engine-to-body seals, forming and gluing with contact cement.
