Phunk they only have the short tailights at that wreckers Im sorry.
The Alfa 105 gtv 2 ltr, Berlina 2000 gt, Alfa Montreal v8 all have them with the live axle finned alloy casing and sump setup as well as other early italian and german sportscars.
The centre for these can be found in many european sports cars as well as luxury cars.
BMWs, Ferraris, Mercedes and many other sprts cars as well as F1 cars use the ZF with 25% brakaway pre loading.
Im trying to find the 3.5 used in some BMWs and Benz but info is hard to come by for this diff housing as all now are independant setups.
