Drew up the side pipes in Sketchup then created a template to clear the pipes.
Printed out the shape of the template to scale on some paper,
Taped onto the body, leveled to the chassis and penciled around the shape
Cut the holes out with an air powered mini saw.
Very easy to control for a neat cut and minimal dust.
Finished off the holes with a file sandpaper taped to a bit of rod in the hand drill.
Also held the vents in place and found the vent holes not very well formed, a bit of sanding and aligning to get the edges parallel.
On the hoist.
