I was just repeating the note I have in the parts drawer with the brackets and should have skipped the 77 drill bit. I use a precision drill press to drill everything and start out with a carbide drill bit which won't wander but is brittle to start the hole and then switch to a regular bit which is more flexible to drill through.
