Wanted 69 back up light assemblies or bezels

Attached are a couple of pics I took of what I believe is a "short" B/U housing. It was another, more informed member's post who made me aware there was a "long" one. Now another new wrinkle a "mid-length". This light when installed on a 1967 barracuda actually points slightly upward rather than toward the ground or straight back so I can understand why the factory tried to correct it. I'd like to see other pics of mid and long to help us all be better informed and so I don't misidentify them to other members. Also, are the lenses and sockets all interchangeable?
