Sundance has a pre-Ford spoiler, and it has two bolt holes at either end, and a hole in the middle leg for the spoiler light cable. It also has a hole to receive a bolt from inside the boot.

So a pre-Ford that needed the spoiler light would have two holes in the tailgate; but Sundance is post-Ford so only has one (no hole needed for the cable, as no spoiler light is intended). When I installed the light I didn't bother drilling a second hole, I just ran the cable into the boot through the bolt hole instead, and the middle of the spoiler is not bolted down. Because the spoiler has two bolts at either end, it's perfectly stable without the middle one. (the green circular thing is a tyre puncture patch, to keep water out of the hole, because the spoiler isn't bolted down)
As for positioning: the middle leg is exactly above the badge on the rear reflector:

You can see dirt marks on the tailgate, after I took the spoiler off to repaint it:

The bolts on either end of the spoiler come through the edge of the tailgate at these points:

The bolts required are M6/16mm "pan head" bolts/screws
