Im not a lawyer, but I have looked into something similar before when I made vintage globe lenses. Technically, I think it is trademark infringement BUT you'll be fine. Not really any different than when I restore an old gas pump and slap a shell sticker on it. Although if it originally was a shell pump than I'm just restoring what was already there, and its even more defendable. (...and how does anyone know that your truck wasnt originally a Chevron truck, right???)
It is more a question of what will get you into trouble. If a company is known to defend their trademark, like Coke, Sinclair, Harley-Davidson, and you are commercially selling something with their logo on it, I would be worried, as there are steep fines per each infringement. You are not doing that, you'll be fine.
