I have a pair of original 67 Shelby or 67 Mustang hipo exhaust manifolds for sale. The parts numbers are C7ZE-9430-A and C7ZE-9431-A. The date codes on these are 2 15 7 and 3 15 7. Both of these manifolds are in excellent condition with next to none pitting on them. One of the manifolds has 2 studs where the other one only has 1. You will be hard pressed to find a nicer pair. Price is $1100 plus shipping. Email gandcmurphy@rogers.com if interested. Thanks.
