I just got a new 28oz balancer and it winds up that it needs a spacer when the company said it didnt. Anyways does anyone know what size the spacer is cause they make a couple different sizes. When I placed both balancers next to each other they are the same height. The only difference is that on the stock 50oz one the raised part where the 4 bolts go is taller. I dont really have anything good here to measure the difference so if anyone knows the size please let me know. Thanks cause I know this is a pain of a question.
