USAC made cages mandatory on midgets and sprints starting with the 1971 season. Champ Dirt cars didn't make cages a requirement until 1972.

Correct. They were “recommended” for midgets and sprint cars approx. mid year 1970 (sorry...that was 50 years ago, so I don’t remember the exact date) and mandatory for the 1971 season. If I remember correctly, “bolt-on” cages were acceptable for two years after they became mandatory, then they had to be an integral part of the chassis/frame.

Did Gil Hess have a cage when he died at Salem in 1970?

According to hamb, after Pat O'Connor at Indy, in 58, they were added to the 59 rule book.

That would have been roll bars, not cages.
