After a bunch of searching, I found that some of the vendors sold their wheels and center caps seperatly. I ended up picking a Cragar 15x8 5x5.5 all the way around. I will run a larger tire in the back to give it the look I am hoping for.
I ended up at about $345 delivered for the 4 wheels from Summit Racing.
While I was surfing the Ford Truck Enthisiasts forums I found a user named Trozi (Jackson) who had a 69 F100 that was beautiful. It became the inspiration vehicle.
