Which alternators fit 4.0 ohv?

[jtaborsky]

I read through the tech article on alternators. It focuses on the alternator options for different years of explorers/rangers. What it does not say is which year alternators are interchangeable.

I suspect a bad alternator on my 1992 4.0 OHV. Will every 4.0 ohv alternator bolt on to my alternator bracket regardless of what year it is? What about 4.0 sohc? What about 4.6 alternators? Am I limited to a 91-94 alternator?

Thanks.

My current job is selling auto parts, and from what I've seen, most of the early to late 90's Ford trucks have the exact same bolt pattern (two on one side, on on the other). The only things to check would be if the connector fits and if the pulley is the same size. Higher amperage might also have a small impact on mileage.
