I am missing two windows from my 1995 International 3800 (Carpenter body). I had been thinking of replacing the windows I don't need as windows with steel plate. Current thinking is not to replace windows but to paint over the outside and glue insulation to the inside rather than spend extra money. The whole reason we use old school busses is because they're cheap.
As I have two missing windows, has anybody any idea what to do with them? I could replace them with sheetmetal or plywood. Alternatively I could get replacement windows but I'm not sure where to go to get them in South Carolina. I certainly don't want to pay a lot nor a lot for shipping.
Check your local salvage yards, and contact schools in your area that might be scraping out older buses
