So i purchased a JDM Supra TT front and rear subframes that came with these axles. Purchased through here.

I'm not sure if they are 6 speed axles though. They aren't the correct length when measured accoding to the Supra manual. Then again neither are my 5 speed axles. Yet they do look thicker. Here are a couple of pics. Tell me what you think.

6 speed axles


5 speed SC axles on top, 6 speed on bottom

 

they look the same...

measure them by standing them up next to each other?

 

One way to tell in addition to the 6 speed axles being thicker is that one of the axles
(not sure if driver or passenger side) is longer than the other.

 

All passenger axles are the same length. All passenger axles are longer than the driver axles.

 

The difference is based on what differential was in the car. The auto lsd diff from the Supra has shorter axles that the non lsd cars because the auto lsd diff is wider that the non lsd unit.
