Just about any local parts store will rent you a puller, but search Ebay for "harmonic balancer puller" and you'll find several dozen of them offered for sale. I use one with a "crow foot" shape that works with either 2 or 3 bolt holes. Stovebolt Chevy 6 balancers have 2 holes, while lots of V8's use 3 holes spaced at a 120 degree angle to each other.
