BMW suspension suitability

[888sp3]

I'm half way through welding my chassis but haven't committed to anything that can't be changed with regard to diff and suspension fitment. I've seen a BMW 316 compact in a scrap yard and was thinking of taking the front uprights and brakes as well as the rear hubs, drive shafts and diff. Does anybody have any knowledge of suitability of these components and ease of fitment. Any help gratefully accepted.
