65 CA77 Left side (battery) cover and my 4 yr old daughter

[versuspop]

I was riding along, after letting my 4 year old daughter help me by screwing my left cover back on, when at some point it flew off. I apparently forgot to check her workmanship. During the ride i heard a strange noise from the other side of the street. I did not think anything of it. Well, the next day, i noticed it was gone. I went to look for it. I walked the entire route I took, and it disappeared into the ether. Anyway...is there a reason there are no single Left Side covers (only sets)on ebay, or is it a coincidence? Also, mine has 2 tabs that come down and fit into the tray. the sets on ebay do not seem to have the tabs. did the design change over the years?

Or, does anyone have one? (even if it is trashed)

here are some pictures of the slots on the battery tray.

Doesn't look stock. Looks like someone did some fabricating.
