i purchased a half shafted and polished TB. teh problem is that it does not match up with my 2002 v6 TB. the one i got is a 01+ TB but on the butterfly valve mine has one little hole in the center and the letters C & G stamped on it. the one i purchased has 2 little holes and the letters D & D stamped on it. i also need to buy a new Throttle Position Sensor (TPS) for the one i purchased but now i don'e know exactly what i have. any help here ?????
