Earle can speak to this much better than I can, but if I remember correctly, the North end zone seating was the student section at the time.
When the endzones were completely enclosed in the '60's, the old bleachers from both endzones were relocated to Livingston where they would become the "home side" seating for UWA which was then Livingston State College. They were replaced several years ago and I don't know what UWA did with them.
