heres the website
http://www.fordf150.net/howto/decode.php
and as for the front diff, it is a 8.8, and its a 28 spline (theres a 31 spline, so be careful, 31 is for the rear)
the rear is most likely a 9.75 and its 34 spline.
before you go out and buy all this stuff, the door sticker will only tell u the axle code (the gear ratio and LS or not)
if u want to find out for sure, crawl under the truck and read the tags that are bolted to the diffs. the tags will tell u everything, the gear ratio, LS or not, and the size.
it will prob read somrthing like this "975 3LS73" for the rear (though if its not limited slip, it wont say LS obviously.)
the front will b something like this "88 373".
