If you like the windows, put them back in when your done.
If your grinding anywhere near them, they should have been removed or covered anyway to prevent damage.
IMO School bus windows suck in every way. No screens, they leak air and water, transmit cold and heat, ect.
If you want a panoramic view, you need to stand or sit in the front of my bus and have a look. The real home windows, combined with the 2 foot roof raise makes for a true panoramic view, with a full site of the sky.
That is something you just don't get with school bus windows and no roof raise.
