I cut off the heads of cyberverse crankcase and crowbar planning to swap the heads via balljoints. So crowbar has a movie accurate SUV alt mode and Crankcase has his altmode from the DOTM game, except he was called "Enforcer" there. Head was a tight fit for car mode. Has to be tilted slightly on the balljoint for the chest to smoothly swivel over it. Peekaboo Used a 3mm double balljoint set from hobbylink joints from Amazon. Cut off the other end of the ball so it's just a one sided ball joint with a peg. Drilled a 1.9mm hole into the neck and glued it in. Great range of motion for the head and the way that I dremeled a hollow circle cavity in the head for the ball socket, was the perfect fit that it very slightly squeezes the socket closer that the balljoint is tighter and not loose like it originally is.
This rules! I'm always happy to see legion/cyberverse -scale customs, especially when they're this clean.
