Need your help please !!

I have a 94 Z28 with a stock rear axle and 4:10 gears. I want to buy a 2001 LS1 rear axle with 3:73 out of a Trans Am and wanted to ask what's the difference between the one I have now and the 2001 axle? I know the gears are different but as far as brakes, rotors,Calipers, length and everything else, will it be just a direct replacement to my 94 axle? What else needs to be done to put this 2001 on my 94?
Thanks a lot for your help in advance.

i thought they were interchangeable mechanicaly, the problem may lie within the ABS. Does the 2001 have tracton control? if it doesnt you should be good

It does not have a traction control, so should it be just a "plug and play" kinda thing? What about the rotors and calipers, aren't they bigger than my 94?

yes the rotors and calipers are bigger on the ls1 cars. you would have to use your backing plates and hard ware on the ls1 rearend. or get ls1 brakes rotors and calipers.

only different if one car had traction control (aka 4 channel) or not(3 channel)

see if it has the sensor on the top of the middle of the housing or not.
