Group,
Papajam is correct. I compared the casting design between my '76 Spider differential, and an old '71 1750 diff. I had underneath the workbench, and the LSD from the '76 has the trangular shaped ribbing. Pretty neat communication between distant locations.

yng,
One arrow points to the triangular shaped ribbing I mentioned. Non-LSDs do not have this triangle. In addition, the second arrow points to the three center cooling fins on the oilpan. These three fins on an LSD rear are longer than the other fins; on non-LSD, the cooling fins are the same length.
