Ken, the alum. heat shld. I used has a thin foam backing that is sticky so I put the sticky side down. Somebody else had used it on their car and that's the way it was installed. At this point, that's the way it is going to be.
Mark, the foot box ventilation is really hi-tech. It is two boat bilge blowers from Overton's, 3" alum. flex duct from Lowes/Home Depot, and the elbows are 45 degree 3" elbows I found at Wal Mart in the RV parts section. I fabbed some shut off valves from alum, and 1/4" rod and then made the push/pull from the two manual choke kits I bought from Advance Auto Parts. The elbows with the valve are mounted on the foot box and the other elbows are mounted on the fender liner at the front.
