Looking for someone that knows how to fix an old corvette.
You can start with Mechanics Files
But your best bet is a Corvette specialty forum like https://www.corvetteforum.com/
Or https://www.digitalcorvettes.com/forums/forumdisplay.php?f=23 or similar.
Besides, we don’t know where you live.
Not only do you not give your location but did not say what is wrong. Many things can be repaired on Corvettes by a good shop . Most likely there is a Corvette club near you so they are always willing to guide Corvette owners .
