The following tags are for the 91 YJ only.
There will be a tag held by two diff cover bolts. Compare the following tag number to what you have:
Rear Dana 35 w/o locking differential:
Tag Ratio
52068008 3.07
52068011 3.55
52068010 4.11
w/ locking differential:
52068007 3.55
52068006 4.11
Front axle ratio should match rear axle ratio.
