Lock, actually the e34 are ""common"" here, the real pain are the e28 parts.
Knowing this, that the e34 is a direct fit to the e28 subframe, will help. I will check if the drum rear is still available to try to do this.

Now, if i cant get it, i will have to go creative, and think about adapting something. Like, if I was to get a set of wilwoods or brembos, wouldnt it just be putting a bracket there to place the caliper and setting everything up?

Never done brakes, so I might sound stupid, sorry about that haha

onovakind67 has described everything very well and it will work for E12 also. I did such swap some years ago.
I addition i may say that the thickness of the drfiveshafts of E28 vary depending on which engine the car was equiped. You'd better go for subframe from m30 car. They are all with thicker driveshafts and have disc brakes (i am from Europe and here most of e28s have drums).
On my car i installed antisway bar from E28. To do this i needed to weld 2 mounting points on the bottom side ot the trunk. I just cut them from E28 and welded them on the exact same place on E12. Unfortunately i don't have any pictures of these. IF you decide to go for e28 antisway bar, keep in mind that they are also 2 types depending on the cover of the differential.
There is one more very good "PLUS" when you go for e28 rear axle - you got the diff with hall-sensor speedometer. So you can easily make your speedometer working with the newer engine and gearbox. I used e28 speedometer gauge and installed it on the place of the original E12 one - you can not notice that it is from another car. Fits perfectly! And you need only 3 wires to connect it. I may have pictures of this, i will search later.
Dimitrov, so looking for what you and onova said, its pretty straight forward, right? All the other mounting points and stuff are the same?

I've checked with the guy who has an E28 and its a 524d, with drums in the back. Its the only one I saw here in Brazil, at all, actually.

Its just pull off the old one, check the mounting of the Diff and mount everything up again? Something like that? Obviously taking the precautions that both of you mentioned.

I will also get the e34 arms with disks to make it happen as well right off the bat, if I manage to get everything.
