exhaust manifold flanges I am needing a pair of exhaust manifold flanges (LH & RH) that will fit 1998 LS1 manifolds. Drivers side has bigger bolt pattern & opening than passengers side. Cant afford what the chevy dealer wants for the new assy. (includes the cats) the only way to buy the flanges new.

It is the flanges that bolt to the manifolds that I need, do you have the flanges that go along with the manifolds? Are the manifolds cast iron or tubes, If so, I would be interested. I am in kansas

Ended up fabing some flanges using the flange gaskets as a pattern. Will be heading to the exhaust shop next week.
