is there a web site where i can find rules for a super stock twd class

you will want to narrow the search down to where you will be pulling. Pulling is unussual in that organizations tend to have slight rule differances between them. Its getting better, but if you plan on building a truck better make sure it fits the rules where you play. And, most times if you study careful, you can make one fit under a couple of differant set of rules. Tell us where you are, and how far you want to limit your travel, and i will tell you of any clubs i know of. All though lower twd classes have faddded off a bit the last few years in many places
