Doug.. yes there is a tag there but I was unable to see any numbers on it.. the choices being 3.31 or 3.58 only.
I'll see if I can loosen that bolt and get a good look at it.
Horror : Thanks ..but mine is 1975. According to the manual its either a 3.31 or 3.58 depending on what gearbox was installed. Problem is that the gearbox has been upgraded to the 5 speed one by a previous owner so I don't know which was the original box.
Anyhow, thanks everyone for pitching in with advice.
I'll keep checking in here. And will re-post with an update as soon as all 4 wheel bearings and seals are replaced and everything fully greased. Then I will know for sure its the diff.
