R ABS front wheel sensors dealer items?

[tdapsr]

Does anyone know if the front abs sensors for a 2000 2wd explorer are dealer only items? I can't seem to find them at my napa store. They have the rear, but not the front.

They typically come with the hub assembly in the aftermarket. I know some people have purchased them separately from the stealer, but for the price, it's almost worth it to just buy a new hub!
