Do you guys know of anything like this? I guess there is some math involved with it to get the correct ratio?
If you do how would I go about doing that?
Then it's definitly not a 66 housing,my bad! If you don't know the history of the diff, it would be a good idea to at least change the oil. I would pull the cover and verify the ratio.
