I am currently gathering parts to change my rear leaf springs, shackels, and upper and lower control arms. I am planning on replacing all the mounting bolts and was wondering if anyone knows what size they are. I need sizes for the leaf main eye and shackel side as well as the bolt that mounts the shackel to the frame and the top and bottom bolts for the upper and lower control arms. I have looked and the info is sparce and scattered. It would be nice to have it in one place. Torque specs would be nice too. Thanks for the help.
