Just bought some new OEM shocks for the Cruiser. Any tips on installation? it looks like I don't need to jack the truck up at all, I can just remove the shocks/replace them? Also, I don't have that socket that fits on the ends of the shock and keeps it from spinning, I've tried an adjustable wrench etc. and they don't work. Do I have to get this socket before installing the shocks? Any other tips are also greatly appreciated!
