The gearbox has two identifying marks. The gearbox type ("016" for an ur-quattro) is cast in the right hand side of the gearbox immediately behind the driveshaft. The identifying letters abd build date are stamped into the top of the bell housing.
Audi's example is "AAU19082" - "AAU" is the gearbox code and should tally with the gearbox code on the stickers in the service book and in the boot. "19" is the day of manufacture, "08" is the month and 2 is the last digit of the year - 19th August 1982. The ratio change occured on 1 September 1983.
The identifying letters are stamped into the casing at the front lower left side. Audi's example is "UR19082" - "UR" is the differential code. "19" is the day of manufacture, "08" is the month and 2 is the last digit of the year - 19th August 1982.
