It's not that the shorter shackles won't line up...it's the fact that they may swing into the shackle relocation brackets.

I made the mistake of trying to do this lift on a budget and not spend the up front (had I done that in the first place, I wouldn't be in this situation). Now that I'm in this situation, I'm about to just say F*** it, buy some 3" leaf packs, and call it a day instead of having to pull the current bastard packs apart and attempt to piece-meal the whole thing together. LOL
