Can anyone recommend a reliable shop to check, repair and recalibrate the guages from the console of a '67?

Yes, I had mine recalibrated at:

Redline Gauge and Clock Repair
469 Windy City Road
Humboldt, TN. 38343
800-375-2310
Mr. John Dvorski

The gentleman did a nice job, cleaned everything, and turnaround time was acceptable. I have had my clock fixed twice in a year, but Mr. Dvorski didn't do the work I had a local clocksmith, they are very tricky, unless you go quartz.

Barry, thanks for the reply, I will call tommorow and get those on the way. I would like to have them in working order when I fire up the rebuilt engine to make sure everything is in order. Again, I appreciate your taking the time to get the address and phone number!
