The differentials are marked in 2 places :
1. Stamped on the top of the differential housing at the front there are a series of letters and numbers the third digit should be a letter and this is the gearset code.
2. Or stamped on the right side of the differential seal carrier which is between the differential housing and the rear flange of the torque tube the second digit is the gearset code letter.
A - 6X43 = 7.167
B - 6X37 = 6.167
C - 8X45 = 5.625
F - 8X39 = 4.875 - 92 SW8 2.2 Auto
G - 8X37 = 4.625
H - 9X38 = 4.222
J - 9X37 = 4.111 - 86-89 Turbo Wagon Auto, XN6 Sedan, 87-? Euro ZDJL Sedan
K - 9X35 = 3.889 - V6-Auto Sedan, 89 ZN3J and Turbo Auto Sedan
L - 9X34 = 3.778
M - 10X37 = 3.700 - V6-Manual Sedan, 89 ZN3J 5-sp Sedan
N - 12X43 = 3.583
P - 13X45 = 3.462 - Turbo Sedan, 89 Turbo 5-sp Sedan
Q - 11X35 = 3.182
R - 13X43 = 3.308

Limited Slip (LSD) was standard in most US-spec 505. The exception is purported to be ABS equipped cars before 1989. In 1989 Turbo models with ABS came equipped with Torsen LSD.
The manufacturer of the ABS systems, Teves (ATE), has recently indicated that their ABS as used in 505 is compatible with all types of LSD

Application Notes
The STIs w/XN6 and 5 spd have the J gears, 37/9= 4.11, a number that makes the heart of any hot rodder beat faster. The XN6 3HP22 SWs have these same gears but W/O the advantage of an overdrive trans the little hemis are close to screaming at 70 mph. The 504 XD2 SWs used the J gears as well so if you ever blow a differential like me in a 85 505 auto SW you can install a differential from an old 504 D SW and only lose the posi (LSD) which was never very posi.
Applications:
505 STI w/XN6 and 5-speed - J
505 STI w/XN6 and 3HP22 - J
504 SW w/XD2 - J
Note: indentical ratios do not assure part interchangeability
