I am working on a '54 3100 and I noticed two things in your finished picture. First, the speader bar under the hood in the back. Is it supposed to touch the underside of the hood or not? Either way, is there some sort of rubber seal that goes between the hood and the spreader bar?
Second, what heater do you have? The Arvin in this truck looks like a dealer installed option or something because it doesn't pass through the firewall in the same location as yours or the factory holes for that matter. TIA.
