How tough would it be to fabricate a new one?

That was pretty much my first response.

I would be inclined to go get a hank of stainless steel rod, bend it
and thread it as appropriate, and install it (if the aircraft is
Experimental) or have it installed in accordance with the FAA's rules
regarding owner-manufacturered parts (if Standard certificated).

I believe that the LS4 has two of those rods, one each right and left,
and that they're generally mirror-images of each other. So you could
copy one to make the other.

If there are forks or clevis or rod ends required, I'd try to buy
matching parts from:
