I just submitted a pretty big order for wheel well liners, bed extender, and the parts to do the 2wd locker mod on my 2011 FX4. Order number is 30589507.
The extender and wheel well liners should be specific to my 2011 FX4 with a 5.5' bed however, the 4wd switch should be the Raptor version that can set the locker in 2wd as well as 4wd hi and low. The TCCM should be for a 2011 Raptor as I believe this is what is needed for the mod to work right.
I believe I ordered everything as it should be, I just wanted to make sure there was no confusion. Feel free to make it ship quick so I have something to play with this weekend.
