I am painting a 1988 Eagle Motorcoach for a local church organization. In addition to paint they want several of the windows "blanked" out. They ask that I remove the glass and replace with metal. I have done this on several other buses in the past but in this case I cannot determine how to remove the windows. It appears that the hinge is held on place with a screw on each side running across the top of the window. I do not see individual hinges that can be removed. Please help...thanks
