What Diff Do I Have?

[-Jimmy-]

Hey Everyone.

When I bought my NA R32 it had been upgraded with some parts including 5 stud conversion and LSD.

I will try not to go too much into the brakes side of things but just on a side note when I bought the car I assumed it had GTS-t calipers and discs as it was 5-stud. I later learned that they were not GTS-t as the rotors were thinner and calipers still 1 pot all round. I did some research and came to the conclusion they must be NA Z32 (300ZX) brakes.

Now a couple of months ago I had an issue where pretty much all of the bolts that hold my driveshaft and halfshaft together fell out. The previous owner used incorrect sized bolts and as a result my car came to pretty much an instant stop while I was driving on the road one day.

So I thought easy done, I will buy new driveshafts and halfshafts and bolts (as they were all damaged in the incident). So I bought some 5 bolt halfshafts from an R33 diff. I recieved them and it didn't fit!? I thought maybe for some reason it had to be from an S13 or R32.

So I managed to borrow my mate's spare LSD from an S13 and took a halfshaft out of it and it didn't fit either. It was the same as the R33 one.

So anyway in the meantime while I searched for my rare half shafts my mate let me bolt his S13 LSD straight into my car.

It took me months but I eventually found pair on Yahoo Japan Auctions! I was stoked.

So the last few days I have been playing round with my diff and shimming it back up so that I can return my mates S13 diff and bolt my old one in.

Basically the question is, why is my diff different to others and has anyone seen these halfshafts before? I have looked at other LSD's and the centre appears the same, I can't find a difference but there must be something.

I am thinking it is from an NA 300ZX aswell but I couldn't be sure, and I have no idea why they would be different.

Here's some pics that might help.

Comparison: Short Shaft

ANY help appreciated
