525e diff will fit into a 320 with a swap of the output shafts and the back cover from an E30 medium case (325) diff.
Why you would want to is another matter. If this is a standard 320, then you'll be lucky to get above third gear when driving it, all you'll be out accelerated by bicycles.

That diff will still be a bit tall for your application, but will be livable with.
Never really studied 525e drive shafts, but I would expect them to be wrong length amnd wrong flange. 320 drive shafts will be OK if you get the output flanges from the same source as the rear cover.
