Next time anyone is under their dashes and happen to have the pot metal instrument cluster removed, take a minute to see how much that puppy weighs. Mine weighed 3 pounds Stock.
I shaved off 1 lb all together by hole saw drilling the real-estate of the back side which is thick walled and was not serving anything and there after taped over the newly cut cavities with good 3M Gaffers White tape to help restore reflection for the inner lights.
