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.

maybe they used the panhard, and replaced the watts with the shocks going forward above the axle

the chassis pics are one end, and that axle bit you see is the other end
