Quick question on 2.3 underdrive pully swap

[chads97grandam]

Im going to be swaping the 2.3 underdrive pully to my 97 grand am. Do i need a new belt or will the one i have work?

I never measured the differences personally - it might be worth a try, but I have a hunch your existing belt will be too large for the tensioner to put enough tension on it. I would pick up a belt beforehand from an auto store for a 94 "Vin A." Either way, it would also be a good time to replace your old worn belt.
