axle swap question

[cleancutranger]

I have a 01 Sport trac and i am needing a passenger side axle shaft for it, do any of you know if a axle shaft from a 99' 4x4 explorer would be the same?
both axles are 8.8's...
the chunk is offset 3" on my sport trac and i don't know if it is on a 99' explorer.

ok sorry i think i found the answer to what i needed to know through the search! lol sorry
I have a 2001 Sport Trac w/drum brakes so i believe it is gonna be a 28 spline rear and the axle in the 99 expo is gonna be a 31 spline so that isn't gonna work i guess...

anybody have a spare passenger side explorer axle shaft they wanna sell? 28 or 31 spline...
