AMA kit question

So i purchased a second hand revo 2012 i think, which needed some love and after re rigging the deck cords and handles ect. im now wanting to upgrade and add some things. specifically an AMA kit with the AI pontoon( NOT the sidekick i hate that ugly floating banana looking thing). Ive been searching everywhere for one but all that comes up is the sidekick. Is it even compatible/fit? and finally where? i've tried the pinned tool search and it does come up but isnt linked to purchase? Do i have to go to a retailer or dealer and not online?

Sorry for all the questions and thank for any guidance!
