Rule #1. Race parts don't leave the owners hands, unless payment is made, "In God we Trust", all others pay cash!
Rule #2. Refer to Rule #1. Tough to do at times, but it does keep the "Honest" people honest, and the others, away from your doors! It only takes one time, for this rule to be broken, for you to become someone to avoid, but that's a good thing, most of the time! Bob
