Will an e34 diff fit in an e30?

[UDelaware30]

I blew up the small case diff yesterday and I have a diff from a 535, its a 3.46 limited slip. The diff mounts differently than the e30 so i will have to change the cover and I need to buy larger flanged half-shafts.
I noticed that pinion has a different flange than the e30. How can i swap that over, and with those changes will the diff fit??

internals will swap as long as they are both small case diffs. but will probably be worth just buying a new one and selling the E34 one.

e34 diff cannot be used.
e30 diffs mount to the subframe completely differently from the e34.
No idea about internals however.
