R200A/C200 LSD options and compatibility

[NicktheMillwright]

Good Evening

 

I figured you lot would have some information regarding axle gear compatibility.

 

Other than my 720, I also have a first gen Frontier, which has a Rear air locker and 5.13 gears on the bench, waiting to go in. Somehow I went down a rabbit hole for LSD options for the R200A Diff, which is what this truck has in the front. I possibly have a set of Warn Manual hubs on the way, and wanted to get a front LSD installed as A, Air lockers are very expensive and B, I'm in there, might as well see if that's a viable option.

 

Ive took to the internet looking for information and have come up with a lot of conflicting results. I know for certain that a C200 and a R200A gears and LSD are interchangeable, but not 100% on which vehicles had them. I think some years of Pathfinders (WD21) some hardbodies and maybe the 200sx, but that it. From what I also gather, spline counts differed as well, which is an issue. The R200A in my truck is 29 spline I believe.

 

The question is two fold:

1. What parts can be interchanged with each other?

2. What cars/trucks had them?

 

There's a lot of late 90s- early 20s Nissans in the yard right now.

 

Thanks

I also wanted to know if there was an easy rear LSD to find for the C200.  There are cheap Chinese LSD's for the R200 I always wondered if they would work in my 4x4 C200 diff.
