Removing Bumperettes From 73 Satellite

[Bruzilla]

I need to remove a set of bumperettes from a 73 Satellite, and was wanting to know if anyone knows what size nuts are used to bolt those onto the bumper? I hate to have to carry a whole socket set back into the junkyard.

bumperettes

bring 9/16 wrench and 9/16 socket and ratchet
also bring propane torch to heat nut some in case of rust.
