I recently investigated clock repair and the $40-50 advertised by Clockworks and Clocks & Guages is their minimum-no parts price. As soon as you start adding parts (which you will), the price goes up steeply from there. A quartz conversion starts at $109. There are do-it-yourself kits for the Vette guys but I don't know if they would work for us. I've had some yet to returned emails to Clocks & Guages asking about this.
The thing that most commonly goes wrong with these is the coil. Rather than a motor, there is a coil that winds a spring. As the spring winds down, electrical contact is made and the coil rewinds the spring. A replacement coil is about $30 and complete internals are about $90.
I watched the e-bay clocks for a long time. The used ones go for around $150 and the NOS for $200 plus. Once in a while they go cheap. I found my '68 for $59 just a few weeks ago because the guy couldn't spell Camaro an so no one found it. I don't know how I found it come to think of it! LOL I was able to repair the coil but it burnt again when what appears to be a broke spring shorted it.
Sonic Motors will sell you a used or NOS clock at roughly the same prices as above.
There is a guy on ebay, skybob1, that auctions repair services that seem very reasonable. I plan to work with him if Clocks & Guages doesn't want my business. I didn't care for the attitude of the person I spoke to at Clockworks so I won't go there either.
