Yeah if I had fiberglass skills I could have brought the bezel closer to the sides of the deck. It is necessary to find a dash bezel out of a donor car so your covered. I used a dremel to widen the opening at the top and bottom of the opening a little at a time until it fit snug. Had to trim it all the way up to the bottom of the vents on the top but i would put the deck in the dash hole mount a coupleof the screws and put the dash bezel over it til i got it to fit nice. The foam i was talking about using is to fill the gap on the sides where there is a gap that you can see all the way back to the mounting brackets and thats what I would have filled in with fiberglass ifI could do it.
