m50b25 conversion help

[Antoe30]

Had planned to do the m52b28 conversion but had trouble with the engine so came across a full 1995 e34 525 so bought it very cheap.
So I have the e34 sump, oil pick up and dipstick already attached, along with the m50 inlet. As far as I know I use e36 engine mounting arms? and I'll be using e28 m5 engine mounts. Il be getting the brake servo from a plastic winged clio. Need help deciding what box, prop and diff to use? And some help figuring out the wiring and the other small bits a pieces?
Thanks

Plenty of info here: http://www.e30zone.net/e30zonewiki/index.php/M5x

IIRC M42 gearbox, m20 flywheel (lightened) and m20 clutch are the preferred combination.
