My 1995 is OBDII. I see most of the shops here (in California) quote ~$100 for a 1995 and older and ~$50 for a 1996-1999. I'm assuming the 1995 and older number is for a non OBDII vehicle? So should my 1995 really be done to the 1996 price? I don't believe the 1995 OBDII trucks have any differences from the later ones correct?
