Got rubber mounted on the wheels and after an alignment was able to register the truck. Below are pics of the rims on the car with good condition white caps and another version with beat up chrome caps.
I like the way the white original caps pop, but I am listing them for sale on the parts board right now. I think, rather than keep the white ones, I am going to paint the chrome ones silver to match the rims, and repaint the spoke black and the bowtie chevy blue.
