i received a PM about the picture on mangosmoothie.ca not all showing, so i went through and found the ones related to the rear narrowed training arms:
Axles are Type 3, Automatic Trans. either left or right - one of them is shorter due to how the AT is placed in the T3. i forget which side. 0.93" shorter, but i shoved the CV in more too (both CV's on each axle) and was able to get 1.5" per side with no issues.
