is it a late 99 or early
 

Trying to figure out if this parts truck I have is a early or late 99
door sticker is gone
does have a 6 speed is that a factor?

Did early 99 have a 6 or were they a 5speed

think you could get either but the 6sp was more common. take the vin into ford and ask them. but if the intake plenums are 3in it is a L99 if there 2.5 its a E99. or if it has the powerstoke badge on the door its probably a L99. if its the sticker on the fender its probably a E99
