The only rules for these cars is that they represent the cars that ran during the 40's, 50's, and 60's era and if they want to participate in on track exhibitions they need to pass a basic safety inspection by an Ozark Vintage Racing Association official.

COMMENTS
These cars are old style vintage cars and need to look like the cars that ran from the 40's up through the mid 60's. We need to keep that in mind. Computer Graphics and lettering look very much out of place on these cars. Old style painted on numbers and sponsor lettering looks much better.

In building these cars, keep in mind that we need and want them to be safe. But, if any modern parts are used for the sake of safety it is better to try to hide them if possible. For instance, aluminum radiators cool better and are less expensive than having a new core put in a 1940's radiator. Using an aluminum radiator you are less likely to have one explode and burn someone, but in the same instance, a little black paint makes it look a lot more vintage.

There is no way to cover every little item in building one of these cars in a set of rules. If you run into something that is not covered, call and ask. We will come up with an answer and it will be added to the rules. (DO NOT start building a car on what you believe to be a loophole in the rules.) Ozark Vintage Stock Car Racing Association reserves the right to approve or not approve any car at any time.
