I went to the first pick-a-part place nearer my house today. I have today and tomorrow off so I like to see what's out there. The first one had a pretty much intact M body and a 1964 Polara with a poly-318.
I drove farther accross town to the next one. I found a 1965 4 door Dodge? It had a poly-318 also and the grill was like perfect.
Then three newer M bodies. I took a factory radiator out of one.
