I've got an Eclipse too. If you line things up right, Dremel a little short, and block-sander the rest, you can get a much better cut in the dash (sorry Rev). I took a little off the left and right, and then the right amount top to bottom. I eventually realized I looked at it in the wrong order (the heater controls wouldn't move) and so I had to cut the upper part of the opening as well, and left, well, see the pics. The sides were cut a little bit too tall because of it.

I had the empeg wedged into the stock brackets where I wanted it, marked it, and then brought it into work and had the case welded in place (just 4 tiny tack welds, I can easily get through with a Dremel some day if I need to).

Just babbling, but as you get in process we'll give some help.
