The best advice I could give anone with a dirt champ car is contact someone in Indycar. They run it and deal with it all the time, and understand it's effect on parts.

It would have been nice for USAC, to put together a couple workshops in conjunction with some Indycar mechanics to discuss these issues.I know that ain't gonna happen though. Still it would be a nice gesture on their part if they did. They need to remember, with no competitors you have no USAC.
