Older Dirt oval Chassis

We have a small flat dirt oval in Southern Kansas, about a 1/15. I am 70 years old and run a 1979 Bug Super Sprint. We have a dozen members. I rank about 5th a moung the 12 karts. We race 212 Stock Appearing Predators. One of our top 3 drivers has a 90's straight chassis Phoniex. We also have Ultramax's, Shadow, Prowler, Phenom, a couple of older Margays. Any of these can win on any giving night.
