Hey thanks alot for your help kenny, My truck is also a 59 f100 4x4, custom cab, I had it shipped in from Texas to my home in NJ. It is truely amazing to see a truck this old with no rust or I should say no rot on it. It is pretty original also so I guess that is why the valve covers are blue. Are you sure about the manifold being red? I would love to see a pic of your truck. Annie
