i was talking to my dad and scanning some of his old race cars onto the computer and a lot 55's, 56's, 1st gen camaros, austins, and anglias were all some sort of modified production class. wtf were the rules on this stuff? i asked him but my dad is the most vague person all the face of the earth sso i figured this would be the place to get some info. i looked on the net, but had no luck
