So I ended not having to double up on the 3/4". I got the stenciling done and jigsawed the pieces, done by 11 pm. Took about a total of 4 hours. I will take pictures of the stencil for whatever it's worth. If you are going to make your own stencil. I recommend using cardboard that is atleast 2-3 layers thick. I say this because on the top hat, the center rubber grommet flairs inward into the base that makes it hard to center and stencil. I eyeballed everything. Also over size all holes a bit. It's an easy job with a decent impact wrench and a helper.
