CT70 rim rings?

[RuppStateNY]

Hi, just wondering if anyone has tried or knows if the 10" CT70 rim rings will work to replace Rupp or Speedway 10"?

I'm pretty sure the CT70 used an 8 bolt pattern. Rupp used a 5 bolt pattern. I think Speedway used an 8 bolt, but I'm not sure if the holes line up or not.
