I’m in the middle of installing my deaver +3s and rpg drop shackles that I painted with steel-it. The drop shackles don’t reuse oem hardware. What size bolt do I need? I don’t know why they wouldn’t include them! Now that I’m committed to finishing this I have to use the oem shackles. Can the drop shackles be put on without removing the leaf springs? Would have been so much easier if I could put them on now!! Advice please.
