Hey guys, i had leveled my truck before i lowered it and to level it,i removed a leaf spring but then once i took it to get lowered,who ever installed my lowering kit cut the bolt so now that i want to add the third leaf spring,the bolt isnt long enough. I think its called a leaf spring eye bolt,it goes in the center of the leaf springs to hold them from sliding, does anyone know the size and grade of it? I have a silverado 2013 LS 1500
