It's an aluminium Dana rear end with new 4.88 gearing (has a LSD) and it is modified to fit in 300-series.
Price is just quite staggering, 1000€, though it is from a Group-F rally car* and rally parts are never cheap.. Expensive but that would take "some" power..

*Group F is a Finnish motorsport class, cars are 2WD cars without turbos and vehicle's international classification has to be expired. Quite a popular class (well most popular if popularity is measured by the number of participants) because cars are not so expensive as in bigger classes and cars vary quite a bit, because new vehicles come in as one's international classification expires. And there are lots of cars like that in here.
