I'm a member over at another forum & there's a member there comtemplating buying a 78' D code short stepside with LRE stacks advertised as "Rare Mighty Truck"

I've checked all my literature & have yet to find it

Have any of you heard of this "mighty truck"
The seller is telling this guy that there were 74 of them made with the majority being black & only 3 other colors offered
