I've seen several attempts at using late model cabs but a lot of them come off looking odd, even that S10 one is a bit too square looking. The biggest problem is that they are so wide compared to the 30's and 40's stuff and the body ends up hanging out over the side of the frame. I've seen some that have been narrowed, better yet is if they are narrowed more at the front of the cab so it has a wedge shape.
You've probably seen this one I did using the lower half of the doors, rear cab corners and rear panel from a 55 Chev pu. The rear of the cab is narrowed 16" and the front 26", roof and cowl handmade, I also tapered the cowl in more to further cut down on the width.
There's a 70's Ford pickup build on here somewhere in the builds that looks pretty kool, they have some neat body lines.
