I have my spare set of 1970 HP exhaust manifolds for sale. I don't know what else they fit, but they came of my 70 RR. These are 2 perfect manifolds. The heat riser has had the repair kit put on it. They were just media blasted & are ready to go. They are date coded October 1969. $ 500 + appx $ 50 shipping to the lower 48 states. PM me if interested.
