I discovered a small issue with this hub when I went to install it. For the Momo horn button receiver (the silver plated plate that goes between the hub and the wheel) to fit correctly, so the horn works, it looks like we need to machine the top of the hub about 1/16" ID bigger. We will just measure the ID on the actual Momo hub and use that measurement for my new hub ID.
And, since we will be doing that, we may machine about 3/16" off the height on the top side as well. Since this is a solid hub, and aluminum, that should not be difficult.
I was very happy when I bolted the new hub on and attached the steering wheel and looked at overall fitment. I think taking 3/16" off will be perfect.
