OK so I am really good at fishing up the info I want from the interweb. My eyes are going crossed at this point.

Back in Feb. of 2010 in the innerspace meg forum, Tobin showed a shining example of his work on the subject. It was titled " mc90 frame and manifold ".

Did he continue to develop, or does he offer that set up on a custom order option, based on unit being mounted?

When I first saw the Gem strapped to the side of a steel 80, I turned my nose up and thought of doubling up some al 40's, for balance and streamlining. When thinking of custom work, I thought of Tobin, I dive his plate and harness now.

If I pull off this gem, I will be calling Tobin.
