Savage gt?

I have a catalog of muscle cars that has a chapter on the savage GT.
I have often wondered if any were actually built ?
Have never heard mention of them in any muscle car magazines, or anything more on the subject. Does anyone have any production numbers, if they were actually produced . And do any survive today ?
I've often thought that it was the inspiration for the 70 Cuda with the middle
of the grille being cut away like that....
