Hi -
No, sorry it is gone. I have nothing left but the memories. My wife and I are now shopping for our next one - which hopefully will be our final retirement RV.
You are talking about the skylight in shower? If you can't find a near close replacement for it, you are probably better off just glassing over it. The natural light was nice in there.
There is place called "Colaws RV salvage" in MO. I think they have some of these old fleetwoods that they are parting out. They sold me some mirrors a few years ago. You might want to check with them.
One my rig, the one nut was all it took to unship the entire mirror.
Good Luck and Happy Trails. Those old Southwinds are good rigs.
