I have oldsmobile cutlass supreme brougham 1982 (Engine V6 3.8L with A/C). I would like to replace the 3 drive belt by myself and I would like to know the size of the belts. I know that the size of the alternator belt size is 10 by 1300. What is the size of the other 2 belts ? I know that best is to remove them and go the part car shope and then buy the correct size (but then I will not able to drive the car.....)
