USCT inboard kit question

-Boosted- said
Just installed the USCT rear springs inboard kit and had one problem. There is no way the shackle bushing will fit into the sleeve that gets welded in. Is there a smaller diameter bushing or did I get the wrong sleeve?

Not sure if you are too far into this to consider these but they make a big difference in freeing up the rear suspension.
