Thanks H, I was more than a bit inspired by all your drawings when I was doing that sketch Pras, I did have to cut the plastic rails out for my Pioneer to fit in the stock opening. You can see the rails were removed in the first photo in the how-to I wrote. For the bezel, I bought a piece of 1/16" black ABS plastic from Amazon and cut the internal opening out by hand with a ruler and Exacto knife first, then trimmed it to fit the dash a bit at a time. If I had been at school when I did the install, I would have laser-cut the bezel for a slightly better fit. The fit right now is pretty good, but there is always room for improvement. My old Pioneer unit came with a bezel that had a pre-cut opening for the unit, and I had to trim it to fit the dash opening.
