The Only 1978 Skybird with T-tops?

I have no idea if this is what it looks like it is. It looks like a real Skybird with a Fisher t-top roof. I got a really big picture (2500 pixels wide) so I got a good look. This might be a really rare car, even one-of-a-kind. The Fisher t-tops came out around December of 1977, and the Skybirds were probably built in January, so it seems like there was an overlap. It should have been difficult for anybody to order one during that interval. It's going to need a lot of work, but of course having the only one in the world does ease the sting.

More recently, I received a build sheet showing, beyond any doubt, a Skybird with Fisher T-tops. The build sheet is incomplete, but it is clearly a 78, because the color code is given as 30. This sounds silly, but I am not 100% sure whether this is exactly the same car. But it is documented proof that there is at least one.

The trim tag from this car shows that it was built the 2nd week of January, 1978.
