I have these caps for the big car rallys. Not perfect but driver with good chrome. $55.00 shipped to the lower 48.
I have the repros for 1970 Electra. You would probably want the 66E which has the red/white/blue trishield logo on a black background. http://www.buickcenters.com/buickwildcat.html Got any questions, send me an email. Mitch
