A few things of note. F-Primus Unicron placed the head on a hybrid ball joint, attached to the neck swivel inherent to the toy. This gives Roadbuster a pretty good range of motion in his head, allowing for some great expressiveness in posing.

IMPORTANT INFO FOR ADVANCED CUSTOMIZERS[/COLOR]
The conversion kit is designed in such a way that if one were to purchase the visor in clear plastic it would allow for EITHER light piping, or for the extra-handy customizer, an LED light. I snipped the existing wires out, personally, because I didn't intend to have Roadbuster shouting that he was Ultra Magnus. I did, however, purchase the clear visor per F-Primusunicron's request. I managed to tint it to a blue I felt was reasonably close to the existing blue on the toy, and I'm actually pretty happy with the result. Though the plastic didn't print as smoothly as I may have preferred, the light piping functions very well (though my photo doesn't do it justice)!
Rest assured, there are NO clearance issues with this toy. The shoulder cannons can flip over and the head has plenty of room on both sides, if you decide you want to display Roadbuster in such a way that it explains his namesake:
Folks, this thing is awesome. For awhile I thought this would never happen, but through the kindness of a stranger who was just as excited about this prospect as I was, we pulled it together. A HUGE THANK YOU to F-Primusunicron for all he did to make this a reality- as you go to purchase this set, PLEASE check out the rest of his shop, he has some really fun accessories for other figures.
