Eldon Match Kit cars were produced starting in 1968 as Eldon's answer to Hot Wheels and to a lesser degree Matchbox cars. Many of the body molds were taken from the Eldon HO slot car bodies, which can be so hard to find today. The match kit cars had shorter or no body screw posts since they were designed with plastic chassis bottoms that snapped to the body, but they can still be mounted to an Eldon or Aurora chassis by making screw posts for them. These are offered mint in box so you might just want to collect these 'as is' since the boxes display quite well. The sides of the match kit boxes are left open, so you can see the color of the body plastic inside even if you don't want to open them. Many of these were made in colors that Eldon never issued for their slot bodies, and they are different colors than Aurora made for thier bodies as well, so these can add some nice color variations to your collection. These boxed kits came with a tree of chrome parts, molded color bodies and bottom plates, wheels, tires, axles, clear windows, decal sheets, and assembly instructions. The boxes measure about 6" wide by 4.5" tall. They are all quite hard to find today.
