Help! Need manifold ideas ASAP. Car going to shop at 1pm today!

Finished dropping the engine (318) in my 67 barracuda, just to find my headers do NOT fit. Im looking for exhaust manifold options. Does anyone know what exhaust manifolds, of what cars/years will fit? I'm desperate, it has an appointment today, at 1pm, at the exhaust shop, to have my mufflers installed. Please, any advice would be much appreciated. Thanks.

And yes. I'm header savvy, they are wrong.

I hear what you are saying but why dont your headers fit? power steering box,drag link or just wont bolt up.Any year a body 318 manifolds should fit. If its a steering coupler hitting theres a different joint. There are several fixes if we know the problem. How hard could it be? Its an a body and a 318.
