Question on tailgate and latch assembly

[Godwick]

Sort of a dumb question, but the PO put this tailgate on without a spare carrier latch assembly and I'm wondering if I can buy the latch assembly and put it on, or if the hole is too wonky. I've never seen one on, which is why I ask, and I don't want to buy the latching assembly just to have it not fit and find out that I need to buy a new tailgate too.
Any help appreciated.

It should work ok even though you gout some rust around the hole there.Go in through the tail gate handle (you will have to take it out)with the backing plate and just bolt the latch to it .It should cover the rust around the edge up until you get ready to fix it right.Or you can cut the rust out the size of a washer and then weld that washer back in place.
