I'm fairly certain that after the early 90s the same knuckles were used for everything - ABS, non ABS, 2wd, 4wd, and all combinations thereof. 91 and maybe 92/3 have 2wd vs 4wd differences but above those years it's all the same forging.
I've got ABS sensors on mine right now actually, the wires are just cut off about 1" out from the sensor.
