The aluminum plate has the advantage of being nearly flush with the cabin top, so no acorn nuts sticking out. This is kind of important for a 6' guy in a 6' cabin. It is easy to manage the corrosion problem with some Duralac and since the thing will be dry now the problem shouldn't recur anyway. The core I'm using under the clutch is crazy high density and wouldn't compress under even very high loading. To make it 110% bulletproof I could drill and fill too. I may have to do a test with a scrap piece to see exactly what happens with this stuff under the high compression of a nut and bolt. Then if it stops raining I could get back up there and fair this out and put it back together.
Below is a side view of this high density core (the dark stuff next to the green Divinycell), it already has two layers of glass on the top and bottom surfaces. Add to that two layers of 20 oz. on top of this core and 10 oz. added to the inner skin before adding this core.
