Bense, if you would like to add this to your trans topic, it would be great.

Thanks to David from synchrotech the genius of trannies. Heres info that can really help.
I have alot of customers ask, i need a lsd but cant tell if its a b16/ls or gsr cause the sticker is ripped off.
3 ways to confirm.
#1 your ring gear. The big hole where the diff fits into. The measurements are close but different. B16 is 116.8 mm and the gsr will measure 119.8. edge to edge
#2 your ring gear face. along the oem ring gear face they both have id lines that run around on the teeth. If it has 2 id lines one top and one bottom its a B16, if it has 1 id line in the middle its a gsr.
#3 stock oem 3rd gear on the main shaft, count the teeth and double count cause they are only 1 off to differentiate the 2. If you count 24 teeth on the main shaft 3rd gear its a B16, if you have 25 teeth than its a gsr.

Hope this helps everyone.
