I suspect someone substituted a piece of tubing for the stick component. Take a look at the bottom, where the stick pivots forward and back. There should be a little steel tube (full length bush) welded in there that captures the transverse AN3 bolt at the base of the stick. If that bush is not there, then you have a not got an original part, just a tube. The plate with 3 holes welded on the front and the bush in the base were present on all kits as far as I know.

Cheers,
