Hasselblad L Grip Mount Size

I picked up a Hassy L grip on the bay for $35 shipped. It's in immaculate condition, however it doesn't seem to fit. My 500cm slides on, but the screw seems much bigger than the threads on the body. Can this be changed out?

Nevermind. Figured out that it's reversible by taking out the small screw on the bottom of the mounting screw.
