Thank you for clearing up all this info for me. I hadn't seen anywhere that i could just swap it straight in, everything i was reading I guess was the earlier models. I actually have an old spare r200 with driveshaft in my shed I'm going to find out what the gear ratio is. Thanks for all the help I really appreciate it.

Oh wow. So what about the halfshafts? Or CVs? Would my bolt on 240 halfshafts work? I guess I can just reading up on the r200 swap. All the posts I had been reading never clarified that the early models required all the different things to swap. I was planning on doing a 5 speed swap as well so that would be easy to take the driveshaft and everything from 1 donor car.

I've looked into the subie swap and I found a diff but it's just way out of my budget. I can't afford to drop $900 as much as I'd like to.

You're talking about the r200 from the zx? I'm trying to avoid having to swap all the stuff required. It's 73 240z I'm trying to retain as much originality as possible. I have found one open 3.9 r180 out of Cali which is $500 and no clue on shipping. I was just wanting to find something I could, worst case scenario, take the gears from and swap into my diff I have now. The ring and pinion gear sets are NLA from Nissan or aftermarket.

I'll start searching thank you

Looking for a 3.9 open r180 differential. I would prefer an LSD but currently not in the budget unless you really want to give me a great deal. Shoot me an email at perryg284@gmail.com. Thanks!
