That steering wheel is not too much different from my 65 El Camino wheel when you put them side-by-side.
@raggedjim, I like the colors you picked!
Keep in mind that you will need to build out the base of the steering wheel where it meets the truck's steering column. Truck steering wheels are a larger diameter at the center. I used a product called "All Metal". It is a body filler that has metal (aluminum) in it and makes for a hard surface when done. If i remember you only need to build it out about 1/8 to 3/16 in.
