So i know you can buy the Model for the carnosaur but there is no Rider so i am just thinking put a oldblood that supposed to go on a coldone on to the Carnosaur. But before i go and spend my money, do they even fit? Cause i dont wanna buy both the things and realize i messed up and wasted money. I am already guessing i might have to do a bit of converstion tho. But before i go and do anything i was just wondering how you guys did yours?
