True trac #914A576 purchased from moser 03 23 2005 and installed in a strange diff with 3 channel ABS. Even called truetrac tech for proper application since it was one of the first sold for 45 degree angle axles.

If you look at the design the left and right sides are not connected with spider gears like a regular diff, the locking action is from the 3 small gears locking in the housing.
I had a lot of concern over this because I thought it was a problem with pressure angle on axles since moser used to use 33 degree and strange has always used 45 degree.
Checked and rechecked it could be I feel it more in my car with the spoon torque arm and semi solid lower control arms.
