I have an O11D with the bitspower water cooling. I was attempting to clean it while replacing the coolant and the gasket that sits between both sides of the distro plate popped out and will not fit back in. I've tried everything, but no matter how I orient it, it seems like it is 1/4 inch too long to fit back in. I don't know if you sell just the gasket itself, or the distro plate without the pump, but I need some sort of help please.
