Seeing as Inferno and Grapple are Voyagers, I was wondering what the scale is between their head and Starscream's head, seeing as Starscream's head is often used as a Menasor head. Is there a smaller scale head that would work better. The Body and limbs go as follows Motormaster: Solar Storm Grappel with reversed body, when in torso mode arms removed at bicep swivel, and shoulder kibble flipped over/ opened into a chestplate Wildrider: Gen. Hot Rod, Vehicle mode standing on robot mode feet Drag Strip: Classics. Dragstrip with one leg unfolded Dead End: RtS Jazz, one leg unfolded Breakdown: Gen. Red Alert, rear bumpers unfolded I'm figuring a stop to a Lego store would be helpful for connector joints. any suggestions?
