Im gonna be installing the 3/4 ton axles and 4" springs and am planning to use stainless bolts. Can someone tell me the sizes and lenghts I will need to purchase. I need the sizes of the front and rear spring bolts, and the front and rear shackle bolts. Are the front and rear bolts the same size?(Front and rear bolt of the same spring?) Also, can someone give me the sizes and lenghts of the body bolts for my 86 K10? Thanks!
