You've already seen replies about where to get GL-4. Regarding the
differential, I don't know whether GL-4 can be used there or not, but I'm
almost positive that motor oil should NOT be used there (even though many
use it successfully in gearboxes and Triumph at one time specified motor
oil in the gearbox). AFAIK, an "extreme pressure hypoy" lubricant is
essential in the differential.
