hey guys im looking to put a lsd in to my gli but i dont have abs and i can get like 4 abs lsd diffs is there any way with out changing centers that i could run one of these diffs in my el any help would be great thnx

They're the same, throw in an ABS one,

The difference is the axle has a chopper wheel behind the flange for the sensor to read.
all parts are interchangeable of the same era.
Make sure you get an EL on for your car, as the upper control arm mounts, handbrake setup and watts link vary between EF and EL.

thank u very much u just made my day :D means i can throw in the one i have sitting here then its back to the drags lol
