Warlord Titan Help!

I have a full size Warlord Titan incoming in a month, and due to Adeptus Titanicus I'm unable to search online for compatible parts for the 24inch titan. I searched for a while, excluding "Adeptus Titanicus" in my searches and sadly due to the lower price and more frequent ownership of the baby Warlords it's all I'm getting. Is anyone able to help in my search?
