I recommend going to Oreilly's Auto Parts for the CV shaft if you are wanting to go with a stock replacement. For the Grand Prix they are about $80.00 to $90.00 depending on which side. This is for New, not Remanufactured CV shafts made by A1 Cardone. There is a 5.00 core when you buy the new shafts.
Part Numbers
Left Side (drivers) .................................................. ..66-1255
Right Side (Passengers) non-supercharged................66-1250
Right Side (passengers) supercharged.......................66-1256
Remans run about 10.00 less, but come with a 50.00 core charge, so get the new.....
