I had a nightmare creating a bezel from scratchand the scrapped it. Bbut I had success modifying an existing bezel.
Does your bezel come out easily? I have a 1998 Dodge Stratus and I mounted my Lilliput directly into my bezel too.
I went to the junkyard and found a plastic bezel from a similar model. I then used this bezel as the "frame" for my modified bezel. I cut out all the holes on the inside with a dremel tool so all I had left was the area of the bezel that held the shape and that clipped into the dash. Next, I got some 1/8 inch plywood that would be used for my new bezel face, cut out the rough shape of the bezel, then cut holes that would fit my Lilliput and a DVD drive. Then I used epoxy to glue the plywood face into place. Next, I used a small amount of Bondo to build up some of the empty area between the plywood and the plastic bezel. Lastly, I sanded the Bondo smooth, then primed, sandedm primed, sanded, primed, sanded, painted sanded, painted sanded... etc.
It came out sweet.
Want pics? I can get them when I go home from work today.
