    Bolted up and works great.
    It fits properly, OK? I took a picture of how I lined mine up. First I test-fitted it without the gasket. I drew a line with a sharpie that matched up with the Delta on the water pump. I took the water pump back off and determined the proper orientation of the gasket. I then bolted it up.I hope it lasts 150,000 miles like the factory one, but I doubt it will.
