That's definitely a 91-95 180SX VLSD, I have the exact same thing. That 4-bolt cooling finned diff cover is only obtainable from JDM S13/180SX that came with VLSD's if I am not mistaken.

JDM S13/180SX 5-Bolt axles are exactly the same length as the USDM 6-Bolt 240SX axles.
The J30 passenger side axle is going to be a hair bit longer, but the J30 driver side axle will be straight bolt on.

I'd recommend you get the Z32 driver side axle (shorter one on a Z32) for your 240SX passenger side axle (longer one on a 240SX) if you're looking for a bolt on 5-bolt axle for the passenger side. The Z32 has a much wider track than the 240SX, so that's why you can use the shorter Z32 axle in place of the longer 240SX axle.

Here's some measurements:

S13 Stock Axle lengths:
(At Rest State) measured from flange to axle end of thread:
- Driver Side: 23.5"
- Passenger Side: 25.0"

J30 Stock Axle Lengths:
(At Rest State) measured from flange to axle end of thread:
- Driver Side: 23.5"
- Passenger Side: 25.5"

[Note the J30 Passenger side axles being 1/2" longer than the 240SX]

I also highly recommend you do NOT use any remanufactured axles from Autozone, Kragen, O'Reilly's, NAPA, etc.. Those are horribly remanufactured axles from A1-CarDone and they will be clicking on you the second you put them on.. Unless you get super lucky and score a good one on your first try.. Most people have to go through 3-6 axles before finding one that doesn't click immediately.. So I'd stick to USED OEM axles if possible! Just look for one that has decent condition CV boots.
