    Most of the GM trucks I've fooled with used 9/16 bolts in the rear,and either 9/16 or 5/8 in the front spring(frontmost bushing,I've seen both sizes)and 7/16 in the rear shackle of the front spring--sorry,but I dont know the exact length,but about 4 or 5 inches should be about right. /forums/images/graemlins/crazy.gif

    4 1/2" long

    Front springs, 9/16 in the front main eye, 7/16 in the rear eye and upper shackle, unless it's 88 or newer, then 1/2"

    Rears all 9/16

    5/8 was not used.
