spring plate removal
 

As part of my suspension refurb I am removing the old spring plates to get the beam blasted, what measurments or mark up do I need to do to ensure the plates go back in the same place when I rebuild ?

any help appreciatedhttps://cimg5.ibsrv.net/gimg/rennlis...4f6f0cefa8.jpg
