I was looking for the Alt on my truck its a 98 single cab f-150. Any idea what size they come stock?

Did you try looking at the actual alternator? Take a very close look at it, and it may tell you the rating in very small print.

yes, there usually is a black sticker with information on it somewhere visible.

Depends on the size of your motor and the number of power accessories. Probably 95 amps possibly 130 amps.
