Erick, sorry for the delay I've only just seen your post.
The ball joint is a paint edge roller - see attached picture - was at Bunnings the other day and they still sell them.
There are photos in the photos section of the Argo navies forum under Garins 16" Lightbridge, the upper clip is a Clipsal 25mm conduit C clip and the bottom support is a 32mm conduit saddle.
