Hey, I am in the process of the shackle flip, and I wanted to replace my shackle bushings at the same time. Problem is, no one seems to have them. Anyone else run into this problem? I have tried Summit, 4Wheel Parts Wholesalers, and all of the local places like O'Reillys, Advance, and AutoZone. Am I going to have to go to the dealer for this? Any info is appreciated!
