rear diff specs on a 91

[OH91awd]

I have looked everywhere only to find specs on a 91 rear diff and the only thing i can come up with is specs for a 93. would a 91 and a 93 rear diff be any different? i have a big 4 bolt rear diff. any help is greatly appreciated.

As long as its a 4 bolt specs should be the same.

The only differences is the gear ratio between an automatic rear axle and a manual rear axle. Also if they are an LSD rear or not, typically the ABS cars were not LSD and the non ABS cars were LSD. You can tell if the car is LSD by rotating one of the rear wheels and if the other rear wheel rotates in the same direction it is an LSD car, if it does not, it is non-LSD. The axles between the two are non-interchangeable.

Also since you asked, all 90-Early 92 Cars were 3 Bolt, thereafter to the end of the 94 production run they were all 4 bolt.
