Shake rattle and roll

I have been looking at pictures online of the LA vs. Magnum balancer and it is definately the wrong part. Just odd because it does have a matching part number with the jegs website for the magnum balancer i ordered but the picture shows a completely different balancer. Oh well. The vibration very minor on the universal dampner I have on it now and I am using the middle sized weight which is correct. Im just going to drive it until I can find the correct part. If I ever build a magnum again I will defiantely keep the serpentine setup and settle for an electric pump. It makes everything easier.
You should not. It's that important. Being out of balance enough for you to feel it can pound the bearings right to pieces.
