The prefered diff here in Oz is the Datsun (nissan) 1600 or 180B diff. This
requires a frame (to bolt to car and carry the spring) and adapters for the
drive shafts, and a shorter adapted tailshaft. All bolts together very
nice!.
I have seen one car with a complete 180B rear end (waste of time), I would
go for the GT6 rotoflex rear end, or a late swing spring.
After much deliberation, my race car is getting a datsun diff and axles
(sliding splines that don't lock up), mated to cut down rotoflex axles (ie
no rotoflex). We'll see how that goes.
Just my opinion.

instead!)
