Question about 65 Darts

I picked up the rear panels, valance, and bumper from a 65 Dart today. I'm hoping to make this stuff work on my 66 and convert to the smaller bumper. The metal is in good shape, so I'm happy.

So my question is about the tail lights. I was able to score three so I'm still missing one. But they could probably use new lenses, and I'd like to change them to the ones with clear centers. I see some on eBay listed for 65 station wagons that have the same shape I think, will they work or no?

Also on the 65 bumper is a light of some sort, is it a backup light or a license plate light?
