OzyDuster74 full rebuild and hemi conversion!!

Glad i got an original scoop as literally just fits onto hood with zero effort..... unlike many fiberglass recreations.
Does anyone know why the bottom part of the twin scoop can screw off?
What holes are usually cut, i dont want to cut the reo as this will cause engineering issues. I was thinking two hundred mm holes left and right of each other.

Tried on the front runners as well, should make the steering nice and light. Still working on the chassis connectors to fit. I want the underside all painted by Christmas and the diff etc in
