Guys need a little help please....Trying to determine whether option pkg 508A included skid plates underneath the truck. I have a 2004 Lariat Supercrew 4X4 and I know the skid plates were optional but I don't see them on my window sticker. I only see "preferred option package 508A"

Anyone know a site where I can confirm what comes in that option package?

 

I have the 508A package. On my sticker it reads
... slip axle
... sliding rear window
trailer tow pack...
...6 CD...
... bed extender
reverse sensing...
... cpt chairs

NO SKID PLATES. I remember seeing the exact same model and color with the plates.
