Ok so I'm wanting to get in to pulling some next year. For now I havent talked my wife into spending more than basicly enough to pull in the work stock class. Anyway i was just reading the rules and wanted some one to clarify the turbo rule. If I understood it correct I would have to run a hx35 housing but could be upgraded internally? Also I think I could have differential lockers if so what brand does everyone recommend. Oh yeah one more question I have a ranch hand front bumper will that pass tech in the work stock class. Thanks guys
