The front plate is complete, but requires fitup, and I've been on vacation all week. the rear is requiring major development to meet my requirements (I'm a toolmaker for pete's sake...) Keep in mind that Aluminum will have to be 3x as thick as the original plate to match the strength, and it will then weigh more. I don't think it's a bad way to go as long as you know what you want (weight vs. looks vs. protection).
