A kaaz. 1.5 way is what i plan on installing. I noticed they sell s4 and s5 as separate part numbers. Im guessing they cant be switched. I bought a tII diff on the web several years ago and im not sure if its an s4 or s5.
How do i find out?

easy way to probably tell would be to look at the lsd unit, the S5 would be viscous and would be a sealed unit, the clutch lsd of the s4 will not be sealed

or you can look at the axel stubs and compare to what mazdatrix has shown here

They pop out. Take two big screwdrivers or pry bars and get behind them and pry out. Sometimes you can get them with your hands.
