The E39 5 series wheels will fit only with concentric rings. The hub on the E34is slightly smaller than that of the E39. Otherwise, the bolt pattern is the same 5 x 120mm. E38 7-series will work and I think E36 3-series might work.
I have old bottlecap 15" wheels, slightly damaged. If you are local to me (NYC), then you can have them if you want them, otherwise I dont think they are worth shipping anywhere far.
