Thanks Guys,
Posting this notice must have triggered something because I just heard back from Dave & Kathy Linquist
I've been trying for 14 days without a reply and then tonight they responded!!!!
They have replied........
<span class="ev_code_BLUE">I think the Corvair Corsa dash comes with a Borg clock. If so, the cost
would be $70 to put a quartz movement in it. Most Corvairs come with a
Westclox unit. If that is the case, the cost to quartz this clock would be
$120.00. In both cases, the clock will be adjusted with the face know and
it will run on the 12 volt system.

From memory they charged me about $70.00 for my Bonneville clock so that seems fair to me. I'll be sending them the clock on Monday.
