Try “The Clock Works”, 1745 Meta Lake Road, Eagle River, Wisconsin, 54521 (800-398-3040), www.clockwks.com . The owner’s name is Jerry Magayne. They did the clock in my 1958 New Yorker Wagon in September 2011. The charge was $59.95 plus shipping, exactly as advertised. Not installed yet, so I cannot confirm it works. But with “over 27,000 serviced” printed on their business card, I am pretty confident.
