I don’t know but the West Germans swear these are the last two in the world and I own more than two broken transmissions that need them.
Unless the marketing firm Porsche stops failing to step up, someone else needs to start making these gears.
Go watch the Atomic Blonde for soundtrack!

Atomic Blonde fifth gears
Made in West Germany, baby, 1987. Two sets of G28.13 gear sets assemblies, airlifted thru time and space. Back when the evil empire controlled half the world and new cars didn’t have “eco buttons” and ten forward gears...

They do that 'notching' thing on the G28.57 layshaft 5th gear as well.

. How did you manage to kill 4th and 5th gear at the same time? :-)

I'm having a lot of the used gears inspected and magnafluxed and then we'll see what's usable and what's not.

Question: Does anyone have used (or new, but probably not) LSD rear ends for sale that could be fitted to an open-differential G28.13?
What have those been going for recently in terms of $?

I think it is time for you to ante up for a billet case...... but then again that is just an idea.

The reason to make a new case would have to be based on some data that would prove or at least strongly indicate that the problem is the case. Then, I think we'd prototype cast it using 3D-printed sand patterns, machine it, and see if the theory was correct. I don't think carving things out of big blank aluminum blocks is where it's at for this kind of project.
In any case, this transmission project is like the US joining WW2. Everything else is completely uncertain and unknown except who's going to win.

Right now, I'd settle for part number 92833205220.
