but its the way they bolt up. chris said something about different gaskets and nut configs.
Hmmm....I would be interested in that too if they did bolt up. I think if it's not the same size in diameter then you'll definately need the gasket to seal it. Even then, I'm not sure if it'll seal it. Let me know how it goes if you do it.
