For all you guys with Turbo Coupes that want a good place to install gauges, here ya go. The factory EQ hole is PERFECT if you use a 3-gauge panel (I have an Autometer aluminum one, I can't say whether or not other ones will fit). All you have to do is go to lowe's and get a sheet of aluminum (or steel, but the aluminum easier to work with) and some small machine screws. Flip the gauge panel over so the mounting "lip" is at the bottom (or you can cut it off if you want), drill two holes near the edges for the screws, and then start measuring in the eq hole (with the trim piece installed) to determine what size to make your brackets. After you make the brackets, it's easy to trim or reshape them to the size you need, but in the end it should fit like this:
It fits like it was MADE for it! Also here's a closeup of one of the brackets:
I ended up only using two screws to hole the whole panel in. It fits tightly enough that it really doesn't need all four.
