Gurney/Savage T/A Barracuda or Posey T/A Challenger Rear Suspension Photos/Pictures?

I've got this one, but it doesn't really help clarify much. Doesn't really look like a traditional shock.

IIRC, the Cudas started with watts link and then swapped over to panhards.

Yes! That's a great shot, thanks. Judging from the large body and that large adjuster screw facing down, it looks like a Koni shock. I was curious if they modified it to a coilover, but it appears to be just the shock.
