All very strange, the good spring has 9, the other has 10 including the broken leaf!. The broken leaf is the one with the locating holes for the clips, I wonder if that is why it was left in along with a replacement leaf?
I have been given a civvy bedford spring, so may use a leaf from that, but also leave one leaf out I guess. Very confused, I have counted the leaves several times to be sure:nut:
