R160 CLSD differential case, replacement source?

[Draker]

I was gifted a blown R160 CLSD. The diff case mounting flange where the ring gear attached decided it wanted a divorce and separated into many pieces. I'm hoping I can locate a replacement case and reassemble it. For reference, part 49 on this diagram.

I'm trying to find a source for a CLSD diff case. Anyone happen to have pictures or know what could be used? Could I use a VLSD R160 case perhaps? I'll pop open a non-lsd R160 and see how that compares. I'm guessing it's different though.

I've been able to confirm the differential case is indeed different between open and LSD units. So the next question is there a difference between a VLSD and CLSD case. Or is there any other case that can be used.

Looking at pictures of the 300zx VLSD it's also different and narrower.

I think the subaru R160 VLSD might be the closest match. I'll see if I can track down a picture of that. Or a exploded diagram or something.

From what I can find on ebay, it appears the VLSD case is different also. So... I guess I'll post a wanted ad for parts and cross my fingers.

Photobucket nonsense all over these pictures, but useful nevertheless.

if you right-click the photo then click open image in new tab, you get it without the PB nonsense. Works on Chrome at least

What abut repairing the 'broken' one? Can it be welded?

The flange shattered into about 10 pieces. It could be welded, but then would need machined.  Not sure I’d trust it after all that work.
