@Paula , you do SUCH a better job than me, I haven't the proper tools or the patience. I love your little power insulators you make, I'd wished I could make those (saw that in a different posting of yours). And you idea on the "counterbore the mounting faces" what a great idea and you are spot on about the gaskets. I have gone though a number of different types and don't like any of them. I more or less have given up finding a perfect fit.
