Axle id on 64 avanti

[Pmaenner]

Hi everyone!  Is there any sort of code or identification on the rear axle that says whether it has twin-traction or not?  

    My rear behaves like an open, just curious if it is supposed to be that or perhaps the clutches are burnt out.

Sometimes there is a tag, but after all of these years you can not depend on that.  Remove the fill/check plug.  Stick your finger in.  If there is space, you have a standard differential.  If you hit something a short ways in, you have a TT differential.  What does the production order for your car call out?  Of course it may have been changed over time.

Bueno!  Thanks for the tip!
