Will any 4.6l alternator work for 99 Cobra

[87whitevert]

I believe my alternator is going and was wondering if any alternator off a 4.6l engine would work or is there a special one for a 4V motor

Alternator for a 99 cobra 4v; will it be compatible with other 4.6l 2v versions from another mustang or truck. or does it have to be for a 4v motor, I have heard that the 4v motor alternator is a bit different.
