Audi 80 (FWD) rear drum to disc conversion...

I have an '88 90 with rear discs here in Arizona that I'm parting out.
I also have rear discs from the same type of car on one of my Coupe
GT's. I swapped over the whole axle, hub to hub. I did it for
aesthetics mostly, as I dislike seeing drums behind revealing wheels.
I have to adjust/fine-tune the brake bias toward the front a bit, as
I've discovered that the rears lock up first. I didn't change the
proportioning valve, but my research at the time indicated it might be
necessary. One is less linear than the other apparently, and more of
a binary, on/off affair. If I can't get it dialed in enough, I'll get
into the proportioning valve issue again.
I can't imagine shipping to SA would be cost effective, I heard that
place has some import tariffs and stuff, trying to protect them from
dangerous outside competition. But let me know if I can help somehow.

I spent time looking through ETKA trying to figure out what parts can be
used that could be sourced locally. I'm in a country where the 80/90 is a
very rare thing.
Some parts are available from the type-44, others need to be bought new, and
the list's good friend Chris Semple over at Force 5 Auto has good prices on
some other required parts.
But in all my looking and checking I overlooked the entire rear axle. Ooops.
Seems this needs to be swapped for one from a 80 with rear discs. I
suspected it, but only noticed it when I finally got pics of the 80's drums.
There's no mounting or the calipers on the axle.
Short of having to bring a complete rear axle into the country, what can be
done with this to fit rear discs?
Doh! Typical dumb me.
