I've actually had Headmasters TFCon Toxin kicking around since 2011, and I was recently fortunate enough to score a second Generation 1 Chromedome body for cheap locally. Needless to say, I finally decided to start the conversion process.
First order of business was to get the colour correct Tech Spec read out. So a donor Generation 1 Weirdwolf which was acquired in the same purchase lot was disassembled. Shockingly, all you needed to do in order to swap the Tech Spec read outs was punch a pin and change them over.
During the dismantling process, each screw was hand polished, and then the factory stickers were removed.
Now he's off to paint and body. lol
