Cast Manifolds from a M-body

I finally got tired of th driver side 318 manifold in 360 powered scamp, so I started looking for CHEAP manifolds. The jeep magnum one almost fit but the collector/outlet is too close to the starter. I pulled one out of a 1981 diplomat with a 318 thinking I would port it again to mate to the 360, but the ports are really close to the 360 no porting required plus the outlet is 1-7/8" and can be ported to 2" diameter.
