I've made at start on my AMT kits that arrived yesterday which will hopefully become slot cars, just fixing the bonnets in place. The Mustang kit is a slightly better fit than the Corvette but both need reinforcing to hold them in place. Thje Mustang bonnet does sit on the body at both front corners but nowhere else and the Corvette just relies on the hinges at the front fitting through the radiator plate but as I'm not using this part the bonnet had to be reinforced all the way around.
