weird speed sensor problem

[romerider153]

ok so i just got a s13 black top front clip and rear sub frame and i have to question about the sub frame one it looks like there is a speed sensor in the rear diff however i thought only the s15 used speed sensor out back and the rest was in the trans. it is a hicas rear end as well and im not all the familiar with them so i didn't know if it was a sensor for that. and to the flange that bolts the axles to the diff is a 6 bolt but not like 3 sets of little bolts its 6 bigger bolts edually spread out now the axles are in good shape so im goin to use them for now but what kind of axles will i have to buy when its time to replace them? thanks

its most likely an ABS sensor,
