I had a glass shower enclosure that was badly etched and was told the only option was a very expensive full replacement. A shower door ain't nothing compared to restoring a Seacraft, so I got out my mega-buffer and some 3M Finesse-It. An hour and some very tired arms later, the glass looked like new. It really becomes a question, like happens so often when working on a Seacraft, of how much trouble you want to go to to save some money.
This picture may give you some ideas for your electronics. Modifying or moving the glove box is not that big a job, but you have to remove the windshield and frame, which you may end up doing anyway to fix the glass.
