Mopar 340 HI-PO exhaust manifolds (68-70)
I have had two sets like this without numbers. They were not repops. I aquired them long enough ago when there wasn't a reason for repops. One set came off of a 1970 Dart swinger 340 auto, the other from a 1970 Duster 340 4spd. . I only recently sold one set on E-bay . It didn't bring any more or less then others I sold.
