I know I kinda screwed up when I was writing the post. Here's what happened. I purchased the 3" spinner and adapter for my YS. With the APC 16X6 it works fine. When I ordered stuff for my Mayhem, I ordered a 2 1/2" thinking it was big enough. At the same time I ordered an adapter for my G26, which I thought I would use on the 3" and put it on my Big Boy. Well as things go, the 2 1/2" doesn't look right on the Mayhem so I went with the 3" on it. So now I have the 2 1/2" spinner and an adapter for the G26. It won't work because the spinner itself bottoms out on the adapter before it touches the backing plate. I'm not cutting anything to make it work. The bolt that holds the spinner to the adapter yes but that won't help the problem. I'll just have to return the spinner for a larger one.
