Actually, there is a guy in Ohio that is popping out the 50s International trucks on Durango frames. He make it sound pretty easy, and he is using nearly everything from the Durango. The 5.7 Hemi was available in a 2004 Durango....

50s trucks are easier to mount on modern frames then 30s-mid 40s cars & trucks. Most of the older stuff is pretty narrow for modern wheel widths. Gene
