I found a stadium promoter's almanac at the Minneapolis Municipal Archives back in 2022 while I was killing time waiting for entry to Monster Jam. it has multiple volumes dating back to the 60s, with precise floor measurements, ceiling measurements, seating capacity, and more. it's ridiculously detailed. it has practically every stadium and arena on the planet in it, up until 2019 last I checked. I posted a lot of what I found for Mario a couple years ago in USHRA and Sim-Monsters, if you want me to sometime this month I can go back and find all the specifics for this stadium and send them your way. Shoot me a DM on Discord if you want.
