2005 part hard to find
 

I am in need of a part for my 2005 Metropolitan that I can not find nor can I find an OEM parts number for it. It is the piece of metal that goes in the back of the fuse box that attaches to the positive terminal of the battery. It centers over the hole for the screw that attaches to the battery and goes down the piece of plastic housing into the fuse box area. Sorry about the poor explanation. I have found what Honda calls the battery box cover (#6 on the parts diagram of the wiring harness) but I do not think this is what I need. Thanks in advance for any help.
