DO NOT USE THAT if it is not laminated safety plate glass! Just a touch from a stone or other road debris and you, and your passenger, could be cut up pretty bad when that windshield becomes a wind-guillotine. Seriously, it is nice to find such a good frame, just change the glass to modern safety specs and enjoy.
dont worry, the car is just a pile of parts sitting in the corner of the garage right now, if it's ever on the road it will have safety glass
