You need what is commonly referred to as a side-loading differential. I believe the original gear ratio for your CSi was 3.25:1. These differentials were only available in E-3, E-9, E-12 or early E-24 (til '82) cars. I don't know which models had the 3.25 gearsets. You could try to get a factory rebuilt from BMW.
E-28 or later E-24 parts are different, as are either E-21 or E-30 323s.
