Thats a good question.
Anarchist dont fit into spectrum because they are neither capitalist or socialist, also they are neither individualistic or collectivist. They are whatever they want, hence anarchism. Pretty much only thing they can agree is that they are anarchist.
Catholic reactionaries predates political revolution that took place in France. They are feudalistic (socialism can be said to be modern feudalism, there are a lot of similarities). This is similar question like asking where does medieval guild system belong on political spectrum or hunter-gatherers. They dont, they predate it.
So when I bring up two ideologies which contradict your simplistic conception of the political spectrum you handwave them away by saying they don't count with special pleading. OK.
Anarchists are variously individualist and collectivist as their type is, but all of them are on the left. Individualist anarchists such as Lysander Spooner were members of the First International alongside socialist and labour parties.
Catholic reactionaries are in fact around today (I've argued with them on the internet), and even outside them conservative/traditionalist Catholic ideological thinking heavily influences the right wing in many countries, e.g. the next Chancellor of Germany.
"Right = individualist and Left = collectivist" doesn't make even the most basic sense when you look at political history or current politics.
