ISO MOPAR to take circle track racing

I've been lurking the MOPAR boards for the last year. I don't have to tell you how expensive some of these cars have become. But like I said, my brother and I would like to take a MOPAR circle track racing. The E body would be ideal but WAAAAY to expensive. So if you have a rolling shell, '68 and up Duster, dart, 'Cuda completely stripped and with decent frame rails that's all we're looking for. Thanks
