Andy, buy the Ipsco part immediately. The orig needs two people, one laying below the car.
If it makes it easier to get room to get the old pulley off, cut the old belt, I assume you need to put on a new belt? My experience says that a new belt needs to be tightened a few times, and if it's not the exact length, it's either impossible to get on, or gets too loose.
Bottom line: buy Ipsco part and the the exact right belt, otherwise it's a nightmare.
