Pioneer makes a good original design type balancer.

The Dorman one is junk, I almost had to beat up on an O-Reilly's part guy that insisted that the Dorman and Pioneer balancers were the same. Not even close, visually different. Some kind of hard silicone for damper on the Dorman, real rubber (like the factory balancer) on the Pioneer.

Then there is the made in china part too...

Oh, Robyn knows a good deal about these rattle box engines, but the Impact idea is a very bad one. Make a fixture or use my 1/2" extension wedged in a strategic area to lock it down and tighten that guy to the required 200 ft. lbs.
