G/day all.
Can anyone tell me when the 3.08 diff ratio became available and on what model.
Local wrecker has one he claims came out of an EH.

l was pretty sure they first came out in the LC Toranas which would be around 1969 so maybe the HK and HT's had them as well-1958GM

As far as I know EH had 3.55 and 3.36 only.

The 3.08 most likely may have been installed sometime later.

My guess is same as 1958 GM's inthat the 3.08 came out around HT/HG,LC/LJ Torana era ( or thereabouts )??.

FC man,
Easy to tell, next to the yolk is a dust plate that has the ratio stamped into it. Also the crown wheel has it stamped onto it as well. Also the 3.08 diffs had two longer bolts at the bottom. 3.08 never came out on the eh model although it may have been changed over the years.
