That's what I was thinking and I'll try to bend them with a touch of a Z to them so I have a lip to rivet some scrap to. I'm also planning double stick velcro to hold the motor in. A faux steering wheel is the next hurdle, maybe a windshield.I like the idea of cutting out for the engine. Maybe cut a letter "I" shaped cut down the middle and fold each side down for the interior engine compartment walls...
