I'm looking for a lower manifold for the V6. Ported, polished, etc doesn't matter. I just need one that has strong threads for bolting the upper manifold to it. I think mine may have stripped a little and I've been unable to torque the upper mani to spec so figured I would try replacing it. Please let me know your shipped price to zip 27713 (or I can travel to pick up if its in NC). Thx.
