Broken tweeters - How do i go about repairing them

So i have a pair of Mission 760 speakers, and the tweeters have stopped playing.
Now my knowledge is very limited, but im asuming the coil is shot, since they just stopped playing.
Ive tested the crossover, and the high pass side works, i've also tested the tweeter, and that definitely doesn't work, so im confident it is the issue.
Looking online it doesn't see that hard to repair, a bag of replacement ferrofluid and a new coil, but please correct me if im wrong.

The issue is i can't figure out what replacement part i would need.
There doesn't seem to be anything online telling me what i should get to fix the tweeter.
I haven't started to pry at the tweeter either, because i am not sure if i want to do that if its not even possible for me to fix it.
All and any tips and help is apriciated.
