This is the quest. It's gained after you do a bunch of quests in Freehold.
The last part is obviously the one you are interested in .. thankfully you can redo just that part by exiting the vehicle before completing the task, or you have to drop and redo the whole quest steps rofl.

Oh and theres a similar quest further in the chain.

Test results ..
Action Bar switching works fine .. apart from the pet bar which didn't come back, but that could be resolved with the pet bar setup nUI has or the pet bar file ( if I was doing this as part of my own addon rofl ), or due to its connection to the main action bar which I hid on the second test along with the overridebar.
Thanks again.
Now to get this working with nUI rofl. Hopefully just that secure stuff will be needed to be added but will see.
