The Energon Pub

For a future custom project I need the head for either energon shockblast or alternator shockblast. I do not reccomend responding if you have a fully complete and good condition one for purchase as it will only be used for parts, and the main thing I need are the heads. I might be able to use the dotm voyager head.
Alternately I could also use a rotf deluxe soundwave, or a rotf deluxe alliance bumblebee.
Thank you

Your best bet will probably be ebay. I've seen a few in the past in various Transformers lots for scrap parts. Thats where I got my extra one from.
