Slant Six Billet Flywheel $250

What pressure plate drill patterns are on this flywheel? it looks like more than one possibly.
I would assume the Borg & Beck 9 1/2" - 10" pattern is there, but what would the other one be?

Thank you.
Itll accept the stock style PP and also what I believe is a Ford PP bolt pattern that the Ram 9.5” clutches use.
