I remember those silver plated brass keys. And I don't think the aluminum keys were a great idea, but they didn't ask me. Probably why they only lasted approx 4 yrs.
Thanks for the luck. Because I'm not sure what the market price is on my car, the auction may be a good way to find out. It will be hard to part with it, but the Mustang would be my only chance to participate in a Mecum auction, so I'm hoping that makes the sale fun.
