That actually does help some. Are you saying the third member from a torque tube will bolt into the open diff of the '55? That would have been helpful if so, but would have been before I sent the other 3.55:1 gears back to Mother Trucker. I'm currently waiting on the 3.38:1 set to come back to me.
Seems Joe said those gears wouldn't fit in the carrier, the pinion is quite different between the 2, when I was looking at them, the shaft is completely different.
EDIT: Update from Mother Trucker, Series 2 3.38:1 r/p on the way!
