OK, so I've been under my car a fair bit lately. And mind you, I've owned this car for over 30 years now. Fairly early on I found the diff cover had been changed out to a heavy duty unit. Never gave that much thought. And a number of years ago, long before I was even a member of this forum, I put in hardened yokes. But today, I noticed these numbers stamped into the bottom of my diff that I never really paid any attention to before.
Now I'm wondering if the 71 on the end might mean this diff is out of a 71?? Anything here tell anyone anything? Ratio? Am I just looking once again at useless numbers? Thanks much for any insight.
