Which halfshafts to use w/ circlip-type R180 Nismo LSD?

Hi all,

Ok so I've got a newer Nismo LSD for an R180 rear end. I say newer because it's intended for a circlip-type halfshaft, not the bolt-through half-shafts which are standard on my 240. So which car should I source the proper shafts from?

Thanks,
