What's the latest on your replacement wheel cover? I painted several about three weeks ago. 'Thought I may be able to help. I may have painted over what you're needing. 'Sorry. New color on mine is ivory - light yellow (#623); original color on three of them was the darker yellow - possibly the color you mentioned. Paint # is on metal data plate on cross bar immediately in front of the radiator on driver side of the hood latch. Plate has, generally, three columns of numbers. Paint # is three digit numer in middle of bottom row of left column of numbers. Let me know your progress, if any, on this.
Happy new year!
