Hello All:
I am seeking some important info.
wbaec7402g0607668 is my 1986 635 csi, and I am not sure what diff ratio it would have, so if you can help me out this would be appreciative.
From this vin number: wbafh8403h1735067 is my 1987 735 csi diff, the question is this a 3.46 lsd?
Lastly, I have a 1979 633 csi and I would like to know what diff is in it as well?
Thank you;
Brian
It likely is the 3.46lsd that came with the car, which you can identify by turning it by hand. IMO a great ratio for a performance based ratio that gives usable 1st gear.
Your 79 would be sideloader type (3.07 maybe) and would not interchange...
