I mentioned before I'd be switching the heads for Classics and Fall Of Cybertron Sideswipes. I did!
Pic 1 - The FOC head on the Classics body!
Pic 2 - the FOC head, with his eyes painted blue! (The piece of plastic that form the "eyes" is too short from the getgo, and hence that is why they don't reach the eye sockets in his face. Not because I shaved them down or that they wouldn't reach because I supeglued the head back together.)
Pic 3 - when you turn his windshield on his back, the head descends into his chest. It FITS! Whee!
There you go.
