Sandy,
The Guards TBD was a Porsche option to the ZF disc type LSD at some point ( I don't recall the year models off the top of my head, but do recall seeing this when I was researching alternatives to the open diff.)

The do have them in the form of a 915/930 carrier as well. The interesting thing is that he mentioned that they might not be what you want if a rear engine car, he said these work great in rear engine cars for autocross but not as well as the clutch type for road race work. The I mentioned that it was a mid-gt40 car and he said they work well in mid engined apps. The problem he mentioned was that they have no ability to bias in decell mode (downshift) and for the porsche folks make it more tricky to drive. For a more stable car like the GT40 (this was my injection of humor) it should work very well. He also made some good comments about a common problem with flipped boxes and reseting of the accel/decell bias as 60/40 becomes 40/60. I still would think about it but sounds right. They also make (I think they are the maker) of a bunch of gears including straight cut and dog box parts for porsches. Very nice to chat with.

To me it only sounds right if the ring gear is swapped across. When the trans is flipped as in most GT40 to obtain the lower engine position everything is still turning the same way. So no change I would think.
