So you finished your 7? Move on to the next step - a pickup truck!
http://smclassiccars.com/other-makes/11 ... mouth.htmlSearch "Powell pickup" and find pictures of some in better shape; this photo set is interesting because it shows the truck is made mostly from single-curvature bent metal. The nose is fiberglass. I haven't found a site that says how the roof was made; it's either fiberglass or domed steel. All the glass is flat. Door hinges are external, the split hood is held down with Jeep latches.
It's a 1950s design contemporary with the 7, so lacked a heater, had simple slider door latches, and apparently no door gaskets or fender lips. But it had optional hubcaps and some really cool optional storage bins...
Looks like, if you can bend a 7 hood and make a nose cone, you'd have all the skills to make a pickup truck like the Powell...
