I have a 82 Sport Coupe with 49220 original miles. I just had to have the turbo rebuilt and can't find gaskets or the ESC sensor for it. GM has dicontinued all of these parts. I got a part number from Before Black for a Fel Pro gasket set but no one was able to find it. Every place I call they say the do not have anything for this car only 84 and up.Any help?
