Review on OEMTOOLS 37187 Harmonic Balancer Steering by Glenn Cartwright

I had to buy to find out because the manufacturer doesn't advertise it anywhere. They lose 3 stars for that. Maximum bolt diameter is 4 inches (outer diameter, not center of bolt). Useless if you need a 4.25" center to center the holes on your balancer. Other than that, it's a pretty well-packaged piece of kit. Threaded shaft end and extension all just 12.9mm (0.5") OD and 2" long. It's worth noting that I put the 'tag' on the bottom of the case, not the top - so everything falls out when you open it. The latches are in the correct position so it's all my fault.
