Nismo GT LSD Axle Problem

[LuckyX2]

So I just picked up a Nismo GT LSD and thought my five bolt axles would work but when I slid the axles out, I found that the portion of the shaft that slides into the passenger side of the diff is longer than the driver's side. In every picture I see of the Nismo, each input is equal in length.

So which cars come with axles that fit the Nismo?

Picture for reference:

See how they're both the same length? My driver's side is like that but my passenger's side is longer.

EDIT: Looks like I need a driver's side Z32 TT axle on the driver's side and a driver's side 90-96 Q45 axle on the passenger side along with Z32 TT rear hubs.

So I counted the splines on the diff and on my axle. My axles are 29 spline and 5 bolt while the diff is 30 spline.

What axles or combo of axles are 30 spline at the diff end and also will fit the Z32 five lug hubs I have in the rear?
Or does that combo not exist and I'll need to go 30 spline hubs too?

The Q45, Z32 TT and late model J30's are all 30 spline, right?
