got my head unit installed in the center a/c vents
All in all not a hard install. After cutting out the ducting itself from behind the vents, it was fairly straight forward. I had to modify the dash pad a bit, but the Metra dash kit filled up most of the space anyway. The dash kit was "borrowed" from my Camaro and fit in the Mustang like a glove. It will look factory installed once I find a way to trim out the indention that the vents left around the the hole in the dash pad. I'll have pics in a few days.
The pics are already taken, but I can't find my USB cable... I think I left it in Houston and my buddy is supposed to mail it to me. So probably a few days. Sorry. I didn't take any 'during' shots, just the finished product (minus the final trim I still need to figure out).
