I was sick of getting unicrons for combiners that come without the crotch panels and the side panels...had a difficult time looking for these parts as well...such that when i found a set, i decided to cast these myself as spare... If anyone would like a set, feel free to contact me...soon i'll be casting the Supreme Starscream's head also...Cheers! update 16 August 2010: Supreme Starscream head completed! Update 03 Nov 2010: Devastator chest plate 95% completed, some touching up to do and it's up!! Update 12 Nov 2010: Devastator chest shield completed! Update 07 Dec 2010: Supreme starscream head now comes with optional light up eyes!
