SOLDHard to find in any condition,and this one is an early take-off, not pitted. Olds dual exhaust was done with the special rear dump driver side manifold, and then the block-off 3 bolt plate fits on the regular p***enger side manifold, where the crossover pipe would have attached. I don't have a parts book for 394 era from 59 to 64, so I can't say what year body styles this will fit. A hamber has said that the 59 and 60 has a different bolt pattern.......but It would definately fit the latest ones, but I don't know more than that. Compare the pics to what might be in the way of the rear dump, if you have an early style body/firewall, or what heads you have on your engine No visable chips or cracks and it rings if tapped, so I am sure it not cracked. 350 plus shipping.
