Chris-
here ya go, she's not pretty, but she's paid for and still works....
Lower alternator shares a mounting point with the original (above) and a Stainless bracket was fabricated to support the lower mount. The stainless bracket mounts to the same holes as the original bracket. Add a longer belt and done.
My amps are mounted on a board that is mounted to the top of the compartment under the observer seat. One battery and a disc changer mounted in the same compartment. There is another amp mounted behind a custom sub enclosure that is wedged under the dash.
Hope it helps.....
