J'ai enfin trouver la liste des codes de PG1
800 PG1 Codes
eg. V4DTUT200001
R = close ratio (type3)
V = close ratio (type2)
W = wide ratio (type4)
C = wide ratio (type6)
4 = final drive ratio (4:40:1)
6 = final drive ratio 3.937:1
D = speedo ratio 1.238 (26/21)
speedo drive teeth on the diff, pretty sure all 6 and 800s are 26 teeth.
T = clutch release lever type (Rover 820)
U = uprated specification
T = Torsen differential
200001 = serial number.

No sticker on the box and looking for a Torsen box?
Look down the diff
Straight through = TorSen
Plate with hole = TorSen
Bar in the middle = Normal.
