That would depend on who manufactured the body. It could require anything from oem to a custom cut windshield. If you are lucky it'll take an off the shelf windshield. Your best bet is to make a template(s) of the windshield (shape AND curvature) and then go out the your local Pick-n-Pull and see what matches. Could take a while.
If you post pics of the car, someone here may be able to identify the kit, which may help you narrow it down a little quicker.
