As you page thru the rule book take a look at the Classic Category rules. The B210 production all happened prior to 1981 so the body is legit for running as a classic. A few years back the Classic category rules only allowed American cars and the engine rules only allowed class E and larger. Those rules then evolved and now foreign cars can run and the engine classes go all the way down through J class. Seems to me that a B210 would make a pretty good gas coupe or altered.
