I kind of doubt that a Hei-coil with such fine threads exists for this application.
First thing though is to measure the length of the shank of the bolt that pulled out the threads.
Then find a longer one and see how far you can thread it in past the damaged threads, and as merziac mentioned you could then cut sharp slots in the longer bolt's threads so that it becomes self-tapping if the threads need to be extended. Hopefully there is enough hole depth to play with.
Longer bolts are available, I would use steel but might settle for aluminum. I doubt that such a fine-threaded tap would be easy to find.
