70T Front Bumper Overriders

I'm trying to remove the Front Bumper Overrriders on my 70T and find that they have a real different head on them. I found reference to them as Cheese Head. Does anyone know where I can get a bit/socket or tool to remove them?

I also removed the Winshield Washer motor from the side of my Washer Bottle and can't get it back on, any Ideas.

I just took the bumper guards off my 1970 and had to use a 6mm hex socket.

I replaced the motor by putting a little grease on the metal bracket, supporting the bottle from the inside with a hammer handel and pressing the motor back on with my hand.

The Bumper overriders is still are still be researched.
