I recently bought a set of used tokico illumina struts and shocks from a friend. I just recieved the struts/shocks themselves but no additional hardware. Does anyone know if the struts/shocks come with any additional hardware when ordered new? I am trying to figure out if they will need any specific nuts/bolts/cup washers. Or will I be able to use all existing hardware and simply just replace the shocks and struts with the new ones? Thanks
