How does the carbon canister mount, to the gas tank?

On the tank in earlier cars there was a hook spot welded to the rib/seam of the tank & a corresponding M6 boss/brkt. welded on the back side with a simple strap that secures the cannister to the tank. Ill look for a pic

Just went through this myself. This is a really good thread on the subject:

Any pictures of how the carbon canister band mounts to the channel on the gas tank?
