Review on Prothane 7 1055 BL Spring Shackle Bushing by Andres Callahan

I have 04 Silverado 4wd 1500 and I will explain my bad review. I never installed it but quickly returned it when I was convinced the metal sleeve was not the right size. There are 2 screw sizes for them (total 6 screws/nuts). The larger 24mm (socket size, not diameter) that goes through the leaf springs on both sides at the front (next to the gas tank on one side). The remaining 4 21mm screws go through the brackets (one through the sheet and one to the body closer to the end of the bed, but both through the bracket). That's the problem. The grommets that go through the back of the wing come with a metal grommet for 24mm when it is 21mm so there is some settling. I don't know why but I returned it for some Nolathanes that have the correct bushings. It will work but it looks like they are trying to make a one size kit so the buyer should be careful. I didn't want any potential noise and rattling so I sent them back.
