Anybody use this 5.9 Magnum balancer?

Professional Products 80012: Powerforce Harmonic Damper Small Block Chrysler/Mopar 318/340/360 - JEGS High Performance

I had problems with mine. Went to degree in my new cam and it was off. I usually don't leave reviews but after I found out it had a 1 month warranty I was a little disappointed hahaha.

I have a local salvage yard looking for a pre 99 bolt on pulley style but if I strike out this one looked nice.
