Hey Rich-

Why not leave that beautiful teak trim and sliding plexiglass and fabricate a flush mount panel that would fit behind it? It would allow you to keep the dash looking orginal....while providing you with the flush mount you are looking for without having to make a very complex lip.

As far as how to fabricate it is concerned, I would think you would need to make a mold out of lauan or mdf. Before I did that...I would see if a common non-stick cookie sheet or something similiar had the dimensions you are looking for.
