Thanks for your reply.
I have noticed that it seems easier to find a better cab for/on a 1, 1 1/2, or 2 ton older truck than a 1/2 ton pickup. It could be the angle of the pictures for the bigger trucks that make the cabs and front clips look bigger to me.
I would like to put together a late 40 early 50 1/2 ton Chevy with a square Omaha Standard box instead of a standard pickup box.
My ultimate goal is to find a 64/65 C80 with a 409 and a working 4 and 5 gear with a two speed rear end, make it road worthy and have some fun.
