Question:

I was thinking about replacing the OEM windows in my 1972 Vega Super Pro car.  What requirements must I follow?

Answer:

In the 2018 NHRA Rulebook, section 4A Super Pro, page 6, WINDSHIELD, WINDOWS it reads “May be replaced with shatterproof material, 1/8-inch-minimum thickness.  OEM windshield may not be cut for scoops, carb, etc.  Windshield/window tint must meet applicable state requirements.  Windows must be closed during races, need not be operable.”
