I have a 3910 that sat out in the weather glazing over the plastic cover before I bought it. ebay has the whole instrument panel for a great price. Takes about 15 minutes to change it. I put one in my 3000 years ago, and recently bought aFord 3600, same problem, fixed it, and Case-IH 395 with the same dash glaze over, different panel hookup and shape, so I bought another one of them and made some mods for it.
When you have a nice looking tractor and nice paint and all and have one of these bleached out instrument panels it just ruins the whole thing. With a new inst. panel its like driving a new tractor.
