First off, I said "MY" rig, and I said the color was the same, not that it was lowered or had rims. It's a 4x4, and won't be lowered, not my thing.
I can't tell you the part number for the Ford keys off the top of my head, a forum search should bring it up. You want the keys out of, or for, a 2000/2001 F150. Spacers can be found on e-bay, 1.5" is the typical I think everyone uses, 2" should work also depending on how high you want to go, though I don't know the safety issues past 1.5. After everything though you will need longer shocks since the stockers will max out on droop. Though if all you do is dd it for awhile I think the shocks could wait, minus to many speed bumps etc. Have to ask someone who's done it.
