I have a 1980. Motor matches the car. My current question is the rear end. The only # I could find was 10 5 79. Is there more #s or is that all. Tanks guys.
Is that cast into the housing or stamped into it?
Should also be some stamped codes, either OF or OH for the 3.07 axle.
One was for the manual the other for the auto but don't know which one is which.
Not familiar with the 80-82 but on the 68-79 they are stamped directly underneath on the bottom, need to lay on your back to see them.
All 1980 cars have 3.07s.
