The trucks have a sentimental value to both me and my dad, and I would prefer to keep the cabs complete. Getting new 1/2 ton front clips is a last resort thing. Grigg can I ask a big favor of you? If you can take a picture of both trucks from the side the same distance away I can use photo shop to overlay the big bolt cab over the small one to see what it looks like. Or I can find side views and scale the cabs the the same size and get the same effect. I was hoping 20" rims would look ok.
