Considering you got such a great deal on those parts, maybe you can pass some of the savings onto Blind Willie, who could use the 57 ECZ-B intake manifold. Shipping by UPS Flat Rate should be about $30, less if delivered to a UPS-authorized facility. Who said, "What comes around, goes around"?

I don’t need it.   I sold one that went to Europe a while ago for $300 plus shipping.   And there’s a few here locally in a salvage yard.
