Hey, I was just curious, if someone went over to
Will Darnell's and bought a set of exhaust manifolds for a 71 Charger R/T , then had second thoughts about weather they were indeed the correct manifolds, and wanted to ask Moparts members if casting # 4890bla bla bla was correct for a 71 440 HP, what kind of badge or special government issued athority would someone need , in order to legally tell the guy he bought the wrong manifolds ?
Without the proper authorization, would giving info make someone come across as looking "high and mighty" Just wondering.
