I have both a 78 and 79 Corvette. Both cars have electrical or dashboard gage issues. Need a good diagnostician and repair person to help me take care of these last few issues. A few examples. Temperature gage worked fine, now not working. Short in charging system. Radio reinstallation. Parasitic battery drain. I have extensive manuals and wiring diagrams.
Please text description of your C3 experience and your rate. If you need the cars brought to your shop that is possible.
