In general, a harmonic balancer puller kit is worth just buying. By the time you rent one or borrow one and mess around replacing the damaged or missing bolts, you have paid for the cheap one (HFT) that works fine. It will also pull steering wheels and looks cool in your toolbox the rest of the time.
You should also have a breaker bar or flex head socket driver so you do not break your ratchet with a pipe on the handle trying to get the harmonic balancer bolt loose.
