Yes, but two of the three studs on the spoiler are broken off.

When I re-fitted mine with one stud broken I did the best repair I could (isopon) and the spoiler now doesn't fit very well on that end because I can't fully pull it down onto the tailgate profile. With two studs gone you would be on a wing and a prayer to be able to use it for anything else than a mould.

Maybe you could put a self tapper in from the tailgate side and hope it bites into the GRP / filler / whatever other bodge can be managed ??
