Extra holes in the trunk?

[ThePoose 37]

Getting ready to repair the hole for the sending unit in the trunk of my coupe and wondering if the holes on either side were factory or put there by the previous owner. They just seemed too well placed and even. Pic below. Thanks.

IIRC on my Coupe it only has one hole there for the sending unit wire.

I had similar hose but higher up. In my case they were for the trailer hitch mount.
