Leaf Spring Lowering Brackets too wide

[BrentBTK]

This truck has been fighting me every step of they way with this suspension. I just moved to the rear yesterday afternoon, and when I went to install the lowering brackets for the leaf springs, they were significantly wider than the perch they sit in. Attached is a photo showing the difference in the center pin on the old bracket vs the new one. Has anyone else had this? The DS2 rear shocks Western Chassis sent were the same way. I had to grind down the pins and the bushings to get everything to fit between the brackets. SSybil is living up to her name, lol.
