Hi,
This is true as I have a book entitled "supercars", which is a history of the winged cars.
It has pictures of both 426 and 429 on the hood.
Also, I am an original superbird owner and although I do not still have it,
I do have the bill of sale and the special parts manual for it.
The cars look fantastic and I am going to build a copy of the one I had.
I will look forward to more photos from you!!
