It most certainly is. Well, I haven't set eyes on that version myself, however almost every other version of KSP and other Steam games can be found on their database so far. It takes some time to search through it, but there is even a step-by-step guide for doing this. Google it (or Bing if you're a masochist) and it will be in the top 10 results. I'd put a link or explain it here, but I don't want to break any rules if there are any against it and I have a thing against doing legwork for other people.
Also, run the game in offline mode in addition to disabling KSP to autoupdate in the future if you depend so much on this mod. It's just easier than acting expectant of someone else to change their behavior; especially people you want something from.
