The column and the head came in to different pieces, so I need to mount them together again. Yes, the plate at the end of the spring should mount to the top of the column, but it's incredible hard to push it in the right place AND screw it to the column.

Good idea to use those two extra holes to something, I just have to figure out something to attach to it wich is easy to deattach after the plate is bolted in place.
