There was a mock-up made. It was then modified into the X-27.If you can get
ahold of the Jay Miller "X-Planes book, it has a lot of info on it.

Does anyone have any links or info on the Lockheed effort back in the 70s
for competition with the YF-16 and YF-17? It was
a derivative of the F-104 but I don't know what happened to the program or
even if a mock up was built.
