Can you buy one header?

Spent even more time on remaking the left header, wish I realised this earlier but I gave up again, its way too hard..
Decided to bite the bullet and save up for dougs or tti`s over winter.
However people seem to have problems with fitting the left header because of the starter. I attached some pics of my starter, could anyone say it this will work or it ill need a mini starter? Also which brand fits better?
So much trouble with this I almost wish I had a nova :P Thanks for all help this forum is a bible.
