you need to use 2 sockets, one to remove the bolts holding on the balancer, and the other to hold the center crank bolt(counter force). I can't remember the bolt size on the center bolt...sorry.....(also be mindful that you may loosen the crank bolt)

Do a search on "balancer removal". Most guys get under the car and patiently tap it off, right side, left side, right side, left side.... I think they use 2X4's. I was lucky and mine was loose enough to wiggle off by hand....
Aslo, you might hit it with PB blaster to help break up the years of oxidation....this will facilitate in removal..

Special tool is required to pull the balancer. If you do not use the proper tool to R&R it, you will damage it AND your crankshaft.
Go to a parts store and rent one.
Be warned: The tool is too long to use with the AC condenser installed.

if you decide to do it the "correct" way, and can rent the Kentmore pully/balancer removal tool, here's a thread with some good info, and a picture of the tool:

No special tool is needed to remove the balancer/dampner. Remove three bolts, and if it's rusted on tap off.
The Kent-Moore tool is for the balancer's hub.

The balancer does not require a tool for removal. Once the 3 bolts are out that secures it to the hub, it will come off. It's it's frozen to the hub, then it can be gently tapped off using a 2x2 and occasionally rotating the engine so you work one side loose and then the other until it "walks" off the hub.The hub can be removed with a regular puller. It's a tight fit but in no way comes in contact with the ac condenser. For LT1/4 engines, GM has a specific tool that makes hub removal a 5 minute job.
Here is a conventional puller I used on my engine during one of my cam swaps...

great info. and advice Jim.... but all he needs to do is tap off the balancer as you suggested, no need to mess with the hub... since he is only replacing his Opti.
