i need a less-yellowed set of buttons for the hvac control. I guess any ‘67 or ‘68 Polara or Monaco with air conditioning would be the same. Please pm me if you have a nice set or full control assembly that you’d like to sell.
Good luck finding the base you need but I think there’s a typo. You need the base with six-inch opening, not five inch. I don’t think you’re going to find a better oil fill breather than the one in the pic.
