Blue painters tape and hole saw in a variable speed drill.
Take your time and go slow, let the drill bit and the Hole saw do the work.
For cuts in body for windshield frame and side pipes I used an air operated small reciprocating saw.
If you think it’s pucker time for the hood and tail gate wait until you do the front jack support tube holes and the side pipe cutouts. On the front jack support tube holes just go straight in and let the edge of the hole saw bit in, take your time.
Good luck,
Jim
