Leaf Spring Lowering Brackets too wide

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.

What year truck are you working with?
What specific "lowering brackets" for the leaf springs are you referring to?

Building a small, high rpm engine with the perfect bore, stroke and rod ratio is very impressive.
It's like a highly skilled Morrocan sword fighter with a Damascus Steel Scimitar.....

Cubic inches is like Indiana Jones with a cheap pistol.

Re: Leaf Spring Lowering Brackets too wide

69-72 2x4 trucks except Longhorns have 2 1/4” wide leaf springs, Longhorns, 4x4’s and square body trucks have 2 1/2” wide springs. OBS or GMT-800 and GMT-900 trucks I have no idea.

Re: Leaf Spring Lowering Brackets too wide

Interesting. It's a '71 GMC. SPID below. Says "Heavy rear springs" I purchased a kit from Western Chassis that included new coils and spindles up front and drop brackets and 4" drop leaves for the rear. The springs themselves are on backorder until February. It was only the base of the brackets that was too wide. (The part that bolts into the pocket on the frame) The top of the brackets where the spring attached is perfect. I had to trim about 1/4" off the pins and sand the bushings down to fit. Same thing with the rear shock bases. I called them while I was in the middle of it, and they had never heard of such a thing... shocking, lol.

My ‘69 short step has the heavy rear springs. They have an additional leaf.
