Hi Chris,
You could consider to disconnect or remove the typebar. Once you can move the typebar in the segment slot, or take it out, you should be able to connect it to the linkage.
To disconnect or remove a typebar you need to move the crescent shaped rod that runs through the segment and acts as a pivot for all typebars. The best approach is to use another "crescent rod" from a parts machine as a tool to push it away. The video below shows how it works:

In case you don't have the extra rod, you can use tape to keep the typebars—except the one you need to remove— in place. Make sure you secure the typebars thoroughly in place so they can't move at all once you have moved the rod. Of course you don't have to remove the rod completely, just far enough to disconnect the desired typebar.
I hope this helps. I want to emphasize that I am not a trained typewriter repairman. I have executed the above methods a couple of times, but not on your machine.
Kind regards,
Lau
