Got a ride today in a customers 1958 B-61 Mack mounted on 1991 W250 ,I don't have the pictures yet but I'm telling you this truck was really nice. He did use a Chevy 1 ton bed though, thats the only down fall. The thing weighs in at approx. 10,000# but still ran out really strong. Anyway just a cool Cummins conversion.
