I found out my duster has one when I ran the numbers off of it. Changed the oil in it just two days ago and it still looks brand new! Side note I changed the oil in my gf jeep and the rear end guts are exactly the same. So if a 96 jeep and a 72 duster both run the same basic setup they had to be good enough to keep using them. Which got me thinking how hard would it be to use axles out of a jeep so I could have the discs and big bolt pattern?
