Gearbox and Prop

[e30hope]

Hi everyone,

I’ve got a 1983 323i Coupe that has a M50B20TU / G260 / 3.23 diff

The G260 is making some bad mechanical noises and since it has to be taken out, I want to install a E36 Getrag 250 that I have in my garage

Could anyone help with what Propshaft I need, I’m getting mixed answers from the forums.

Any help appreciated.

Thanks!
