Probably a good idea to go back with safety glass if you can. There is a reason it has been a requirement in new cars for more than 60 years that I know of. This was one of the earliest mandated changes for new cars and for good reason. There are some clubs that even require it as an updated safety measure before judging. If you do make the upgrade, ensure that the “safety glass” etch is visible after installation, to prove it has been changed. In a crash, the old style glass splinter into swords that will slice and dice all the occupants in the car.
