Other than the small spacer and how the sway bar end is designed, I'm not sure what the difference is between these two desigens.
One more thought for anyone contemplating a fix for this: any rearward sloping of the anti-roll bar would contribute to the twisting action. More precisely, if the anti-roll bar arms are anything but at a right angle to the vertical links, they exert some non-vertical on the pivots.
This is conceptually simple to fix with a change to the vertical link length. In reality I think SPF GT40 rear rear-antiroll bars by design slope about 30 degrees, so if twisting is the problem here, that's just making it worse, or could even be the root cause. See the SPF on the left vs. P1015 on the right:

FWIW, here's how the sway bars were mounted properly:
This is P/1080, a late Gulf-spec car. I deliberately shot closeup photos of the sway bar mounting because I was highly dubious of the SPF scheme, which seemed decidedly amateurish in comparison, and in the someday-faraway-future when I do finally get my GT40, I was going to have my car converted to follow the factory specification before it ever turned a wheel on the road.
Note that there is a sturdy and reinforced inverted U-shaped chingus which is captured by the shock mounting bolt; the sway bar is then contained in sturdy aluminum blocks which are bolted to said chingus.

So, to implement the fix portrayed below, I would either need to replace my exhaust system or the sway bar. Obviously, the sway bar would be cheaper! :laugh:
Although a few cars appear to have the SPF style of sway bar mount, by far the most common mounts are as you have shown.
...I have not "tracked" this car, nothing but alot of "relatively" calm street driveing!
Guys--just FYI, check out the solution that Chris has employed on his genuine GT40 P/1079.
