Hey I remember that post. Oh yea because I made it. Lol but a agree it is very frustrating trying to install parts when it comes with 3 diffrent weights and no instructions on which one goes with which engine. Lol also I be upfront and say I am not very impressed with this balancer. What I am talking about PRW must only put just enough powder coat on it to cover it and that's it. The frist one I got almost all the powder coat was rubbed off the back and some of the outer ring wear the timing Mark's were. Also one of the counter weights was lose in the box and just floating around. I will say summit took it back with no problems and sent out another one, before I could send the bad one back.
