The funny thing is only NKA has verbiage directly addressing anything related to slip joints. Not a single rule book I have read uses the verbiage continous anywhere in them besides for champ cages. So I'm not sure how anyone ever got the idea this was a rule. Welding does make a tube continous, but the rules never once even mention this. I knew what the original argument was about whi h was mentioned in the other thread. But, Charger also ran a slip joint, and it's legal because it's not mentioned in the rules.
