4x4 Center Dump Exhaust Manifolds

[Ironhorse]

Have pair of GM center dump exhaust manifolds for a 4x4 application. Pre-smog tube pieces w/o the A.I.R tube holes. Nice condition, no cracks, no chips with normal cast surface. All three studs are intact on each piece, good threads and straight. Have both metal collector pipe rings and also a cast iron heat riser section which has the baffle plate removed. Heat riser was used as a spacer section only. Placed the collector rings and baffle on each manifold to show the exhaust studs are straight, not bent. Looking for input on fair value of all five pieces.
