Plus, I've read that it's likely that all Turbo Trans Ams came with 4 wheel discs, whether the car had WS6 or not. So, that's another case where having 4 wheel discs doesn't necessarily mean the car has WS6.

The front sway bars are all the same size, 1.25", so it's not larger than any other. The rear sway bar is the one that's normally larger with WS6 being 3/4" compared to 5/8" for standard. That would be another clue to whether it's WS6 or not.

I read a recent post where I believe somebody said they found a 5/8 rear bar on a WS6 81, instead of a 3/4 rear bar. That might have been a case of them thinking it was a WS6 car due to 4 wheel discs, when it could've just had the J65 option without WS6.

Another visual clue to WS6 is 2 extra braces installed on the front lower control arm mounting points, like in this picture:

Easy tell tales:
The sway bars on WS6 cars had hard white plastic link bushings-Problem with those is they didn't last long because not flexible they split and cracked. Most replaced them with readily available black rubber.
the car the OP posted has Turbo wheels which are WS6. Of course the PHS will speak volumes.
With all that being said, what Grand73Am said is the easiest tell. The brackets. WS6 only.
There is a bunch of other things of course, sway bars, shocks, steering box etc. but in the field; the brackets.
