I was thinking this...

I was thinking this was a pack of two wingnuts to replace my original battery box ones. Very expensive for a single replacement wingnut!

Just what I needed!

I don’t know where I lost one of these, but I did. I finally decided to order the OEM part. It’s much better looking than just a normal wing nut. This makes the battery box look much better, and it functions flawlessly! It was also sent and delivered really fast.

Perfect fit; solved the problem.
