First of all, it would be helpful to know what trans are you running,
W58 or a R154? Most likely you're running the R154 trans since your spinning one wheel all over town. Your best bet would be to go with the Supra or Aristo Auto TT diff. The gear ratio is 3.76 so you should be good to go!

 

Yo you know what I cant even remember what tranny I have on lol holy ***** all I remember is that the guy who sold it to me told me told me it was the 1 that it came with SC's from factory.

 

That is a w58!

 

This is my tranny just in case sum 1 know what it is just by looking at it

 

This triggered something in my head and I've never thought about it before. Do the engine importers (JHot, etc) also have diffs available? Finding a legit Supra TT diff in a junkyard or CL or something is pretty much impossible, but what about an imported Aristo diff?

 

Any 1 know?

 

there is tomei. but i think kaaz is the same thing or very similar.
