Here are some pictures of the Bud cowls and setup.
I attach the front cowl with a pin at the nose and some tabs glued to the cockpit at the back, use some screws into the engine well wall to hold it .
That U10 had some blocks glued to the engine well for the tabs to screw into but i found i could just glue some tabs on the inside edge of the cowl and run the screws thru the engine well wall. The center scoop will have some pins thru the front cockpit bulkhead and some sort of latch at the rear to hold it down,
I was working on a new U10 and will have some better pictures soon.Thanks Phil,thats what I was looking for.
