Can't help you with when they changed it, but yes, they did make them back in 02. That's when the one in the top of this pic was made, the bottom one was made in 07.

Yeah I know what you mean. I had my planed after the extra material was welded on, just to insure that it would still seal properly. Didnt have much taken off, and the gasket was thick enough to offset it..
