Re: [AMC-List] Re; Exhaust Manifold Mystery

The tranny and engine appear to have been original on the Matador.  Hard to 
know for sure, of course.  The good news here is that the manifolds from the 
Wagoneer will probably fit on the Matador.  My son is wanting to use them 
when he puts his 360 back in after he's rebuilt it.
