if you've got drop brackets you'll have these or something similar between the sway bar bush and your chassis and the swaybar will be under the muffler..
Too late to get a tape measure out but if you've got standard rear sway links the swaybar will point down noticably and the links are maybe about 9" long iirc. If you have longer sway links the bar will be about level or possibly pointing upwards a touch and the links will probably be about 11-12" long.
Depends what shocks you have fitted but its likely your shocks will fully extend before your sway links stop downward travel of your axle. The other way around leads to bending links.
Theres probably nothing wrong with yours. Just the sway bar doing what sway bars do. My rear wheels have come off the ground over steep ledges and road sides if angling up them.
If you don't know whats on your car perhaps contact DBOR and see if they can tell you either by providing them photos or maybe they can search off numberplate or old owners name or something.
