1C6SRFHT0MN511093. Window sticker said ORG, too, I believe. It certainly could have been messed with by the original owner (I bought mine CPO from a dealer). I didn't take pics but the measurements on normal are: LF: 20.7, RF:21.3, LR: 23, RR: 23.5. I never measured pre-repair job but can see and feel that there is now a rake to the truck and can feel the difference, especially in the front. If I just throw on OEM links, set the truck with those and then reinstall the leveling links, would that set the level automatically to where it was? I pulled the Revel Links off this morning but the adjustability is in accessible because the screw and nut are frozen. (will attempt to unfreeze them later but need the truck later so don't want to disable it entirely if I screw something up.)
