Original Hydra- Help needed -Female twist lock

Thanks, I was unable to find the item at Lowe's or Home Depot.
I did however find it on line at Parts Express.

Now I need to find Male IEC's not the chassis mount. I have bought them in the past but I cant find them now .

What I am trying to do is create an adapter so that I can try out various Power cords befor settling on one and changing the end.

HELLO, THIS IS WHAT, YOU NEED, A NEMA L6-15 LOCKING RECEPTACLE,15A/250V.YOU CAN BUY FROM PARTS EXPRES,$14.55,OR WHERE YOU LIVE AT AN ELECTRICAL STORE. I HAVE DONE THIS MY SELF.

I think that is a standard plug type for 220v. Any electrical supply or likely Home depot has it...
