Looking For Left-hand Battery Side Cover For 2007 American

I was able to find a right side cover on eBay for this, but I even went on the triumph parts website where they list the right hand side cover but no left-hand side cover searches have come up empty for a part number or even an illustration. anybody know where I can get the cover for this?

 

Thanks but I wonder what goes into the nut tab welded onto the frame on the rear side of the battery….
