I just went through this like 3 weeks ago. You need to get an input flang from a 280z with a r200 in it. Its a round flange. If i had an extra one i would send it to ya but i dont. Thats how i actually got my lsd i was swapping out my r200 from my turbo zxt into my my 260 which had the r180. So i went to my friends house to see if he had one and he did but it was on a lsd and was about to take it off and i was like, well how much for the whole thing. He said i $100 bucks and i said sold before he even finished saying it lol. Good luck finding one.
