That's what I wanted to know, thank you!
I called Classic Industries today and gave them the width measurements of my hood, and they were very nice and said they would measure and get back to me. Neither of us wants me to buy an $800 hood and have it be wrong.. but wow I'm looking forward to chunks of rust not literally falling off my hood every time I open it!
I measured the bottom lip, outside edge to outside edge, and it seems to vary between 74 1/2" to 75" but that's not a surprise given how old, rusted, and not straight my hood is. It measured 78 5/16" across the widest part of the hood, tape measure across the back and ends at the widest portion of the flare line. I guess I was just nervous about spending that kinda coin and having to pay shipping back on a 150lb hood that was wrong. But anyway..
Kinda figured on the inner fenders. On my bus, the inner fender goes inside of the steering shaft; the box is outside the frame and you can see the whole thing from outside the wheel well. Inside the engine bay, you can't see the steering shaft. On the small trucks, the fender well is outside the steering shaft, which can be seen from inside the engine bay, at least on the ones I've seen pictures of. Dang it. So probably no aftermarket inner fender well love for the big bolt :-(
