I know this is resolved, but pro tip for this kind of project: Get those snack ziplock baggies, each type of screw, or fastener, put em in their own baggy together and write on it with a permanent marker where it came from. For a dash, toss each baggy in the glovebox that you've already taken out.
Makes life so much better... especially if the project draws out.
My dad who was a master tech taught me to use muffin tins. Do course this was 40 years ago.
