Socket size and type for PS gearbox removal

[Sonny]

Looks like a special socket is required to remove the ps gearbox from the frame of my ‘70 Belvedere. Can someone tell me the socket type and size? Or at least the socket type. Thanks

Cant recall the size but just a 12 point socket

Thanks! Maybe I’ll just buy a set.

Pretty sure its 9/16.

I'm thinking it may be 1/2".
