A 73 has a sway bar on the rear? I think you may be mistaken.
The only year I thought that had the sway bar mounts was the 69 maybe 70, and it was just because they were using up some stock from the euro bound GT's so it only made it on a few that came over here.
Someone must have added it then. Or maybe your car is a gray market, or even a one of a kind. You can eaisly enough add the sway bars. In the 200+ GT's that I have looked at in person none of the gts had sway bars in the rear, only a few early models had the Axle mounts for them. All gt's have the body mounts and the mounts for the front sway bars. I have also owned three 73 GTs and none of them had the mounts on the axle for the sway bars, I wish they did, the GT needs them.
I rembember reading a report years ago on the subject of GT sway bars. I don't rembember the source, but the author calimed that sway bars were an option in the european models but were not installed on the cars sent to the states due to cost reduction and the claim that Americans did not like firm handeling sports cars. Still have not figured out whare that batch of American motorists live.

this is what i also herd also in the Blitz or maybe that book with all the GT articles
it is very common to swap in a sway bar axle in to a GT
i got one out of a 68 rally Kaddet for $50 (3.67 rear)
Pappy of Pappymotive did a 4X4 GT years ago
he is an Opel GT circle track racer down in Corpus Christi TX
