Does anyone have a source(s) that calibrates Camaro 1st Gen (GM in general) tachometers?
How happy where you with their service and what is the average costs?
The tack in my ’69 is in good shape cosmetically but I need to verify its calibration. An initial review thru a web search I found Auto Instruments located in Collinsville, VA, autoinstrunments.com, 276-647-550.
Thanks in advance for your recommendations and feedback!
