Harmonic Balancer Installation Tool

Buy the correct tool. I did many many ballancers with a block of wood and a hammer, while doing cam swaps. Because I was too cheap to spend $60 on the tool. Then I carry on business as usual and stripped all the threads out of a crank. It ended up costing me about $300 to fix my mistake, on a car that I get paid $800. It really eats into your profit when your buying everything to devils a motor, vs buying the tool.
