1960? Six Flags arrow car

okay here is my first true mystery item. i bought this car and have very few clues as to its origin. i know its an arrow car from 6 flags late 60's early 70's, however i dont know of its rarity, or what kind of market/history there is to this. i was able to find a guy that has one of these cars, and he has been very helpful in identifiying this car and finding parts. there are apparently one 3 of these in the st. louis area. this car is fiberglass, with a full h frame that a car would have, only minified. headlights, blinker, brakes, a 7hp kohler engine that im going to replace hopefully with an 18hp b & s. has original windshield frame but no glass in it. the bumpers aregiant springs. tires are air and are the size of a go carts. pretty much a small car. planning on intstalling a radio, adding a hood scoop/ mock blower, chrome non working tailpipes, chrome rims, chrome side stripes, and rechroming the windshield bar, and the bumper. if anyone knows anything/anyone/or want to talk about helping me on this, my name is scott and my number is 1618 791 9451, thanks and enjoy!
