I had a Truetrac installed and it requires non-LSD stubs for the diff. I'm guessing that Cressida or automatic supra stubs will do the job.
Here is a pic of them:The non LSD only works on the #342 trutrac, the original one. No longer available. The #644 replacement which is what i have and which is sold now, the non lsd stubs are not long enough to clip. Longer but not enough to clip, i tried. What i did now is have my splines reduced to fit lsd stubs which are easier to find.
