Part number FTS208 - Fabtech 1.5" rear add-a-leaf for 99-04 Ford Super Duty pickups. Used but in great shape. Pic is from the interwebs, but you get the idea.
They weren't on my Ex, and honestly, I can't remember how I ended up with them, but I don't think they've ever been installed on anything. They are listed online as 1.5" lift.
Oh ya, listed right in your description. I think it would be a good addition. I've been wanting add-a-leaves for a while to reduce the dependence on the airbags. I'll take them.
