Are you doing the rat rod thing? Even if you're not, man I think those seats will look really out of place.
I had thought of taking my little motor and building a big soap box derby car body and frame for it. Make it out of aluminum and rivet it and polish it up sorta like a P-51 body. Maybe paint up the nose a bit and put a pin-up girl on each side of the engine sides. I intended on running straight axles so the body would sit up sorta high off the ground and use some solid wheels that use Model A sized tires, tall and skinny. There would be no front brakes and the rear brakes would just be a rotor attached to the pinion on the third member. The sides and top of the hood would have the long louvers cut in and thered be a scoop under the nose to relieve under hood temps, but there wouldn't be an opening up front, the radiator would be mounted flat under the seat or towards the rear of the body up under it. Tail lights would be tiny and likely mounted to the rear axle and I'm not sure about headlights. Turn signals would be little LED's. A small Lexan windscreen, no doors, just a little round step that jutted out from under the body or a little step that flipped out and then back in. It would have a full belly pan that rolled under except for the radiator. It's a one seater and would have a little Cobra roll bar sticking up or it may be covered up by a headrest pod that tapered back onto the body. It'd have a little vinyl cover that snapped over the driver's compartment when not in use to keep out rain and prying eyes. No radio, no heater, Shelby competition bullet mirrors, Sprint car steering box with an arm that stuck outside of the bodywork.
I figure a half helmet and a set of goggles since there's no wipers. What do you think of my idea?
