Tony,
We left the differential out because the price difference between a Jaguar and the aluminum differential is quite substantial. Really, they both perform the same so that is a way someone can save some dough if they want to.
Of course, the aluminum one will fit in there as well. It is right at 40 lbs lighter than the original, (or Jaguar), differential unit.
Kanuck,
That is a "cut and paste" error. I guess it really has been a LOOOONNNNGGGG time since we have had an ebay auction. We have simply been way too busy to even breath lately. The car is made to our latest specifications--of course, those specifications are constantly changing and updating.
