I supposably got a set of pink rods, are they all supposed to have the number "386" on them? on the bottom of the rod they all have different cast #'s (264,212,265 ect.ect) of course there are no pink on them anywhere. they all have GM on them does that matter on telling if there the real deal or not? whats the best way to know if there a real set for a 69z 302? they all do have the raised cast letter O on the caps. thanks for all you guys help.
