Hi Greg, Just went through an ordeal with my 54....had a local "professional" glass company supply the windshield and do the installation. The guy seemed knowledgable...had the glass in in less than 15 minutes...snapped the deluxe trim in and was off like a rocket. It looked okay but the first time I hit a HEAVY rain it was a flood in the cab. Seems that the 54 windshield requires sealing and that the trim goes on before the glass is set. The dufus had the gasket 90 degrees out of phase and no sealer.
I contacted them and after a short conversation took it to another company who spent 3 hours with an experienced crew to get it in correctly. Obviously, the charge was significant along with a new gasket. So if you have a 54 find out beforehand, if the installers know how to do it and give it a water test before money is exchanged. I hope this saves someone else a lot of frustration...and money!
