Leaking power steering pump questioin?

[ArkLightning]

Looks like the shaft seal has gone bad on the power steering pump on my 15k miles Lightning. Is there any need to buy a replacement directly from Ford - in other words, was the Lightning PS pump specific to the Lightning or is it standard F150 stuff? If specific to the Lightning has anyone found if Autozone or Advance or NAPA stock it?

Thanks

Pump is not specific.
