Driver side “old” windshield into a different coach

Several years ago I had both windshields reset on my 96 Southwind because of leaks.
I found glass shop that worked on motor homes. They removed, resealed and replaced both windshields using the original gasket. They never leaked again.
Keep looking, you will find someone who can do the work. Check with local dealers and body shops. Maybe your insurance agent can direct you to a qualified shop or installer.
