When I called them last year about windscreens for the kit cars they said they didn’t do tempered glass
Just have them made from modified impact acrylic. Better than polycarbonate as that material doesn’t absorb moisture(why headlight covere eventually get that haze shit on them) Various impact levels, but typically 80-100 MIA is what you’ll use. Thermoforms easily as well, so shaping the countor to fit the doors isn’t difficult.
More scratch resistant than polycarbonate as well, just more expensive. Still going to be FAR cheaper than having custom tempered glass windows made. you DO NOT want to use regular glass.
