according to my 1948 chevy truck restoration packet, chrome grille and 5-window cab were separate options from the deluxe cab option. It does however state that the body colored wheels were part of the "RPO 390 deluxe equipment". The packet didn't come with the RPO options, so I don't have a breakdown of the options or what RPO 390 came with. Everyone else has body colored rims so how will know. Since the color is Cape Maroon, the pin stripe color should be Gold. One stripe on the beltline and 3 on the rims, if using 16 inch, none for 15 inch and 2 for 17 inch. I'm sure this info would be the same for 1950 also. Call 1-800-222-1020 and order a free packet. Just give the year and vin.
