I'll be putting my complete mod work steps on the mod thread when this is further along. But here's an update after waiting a long while for parts to come in. I got the small and large stainless steel dental expanders from China via Ebay (20 pcs) for a total of $50. That's by far the most expensive part of the mods. It kills me to spend $50 on these things for a $100 helmet. But other parts came cheaply so I win and lose some. Working on the back neck piece first, I tried removing the gold paint with paint thinner. It worked okay but the safer bet was to just use a black paint pen. So I ended up doing that to cover up all the gold paint on the original expanders. Then, I was worried about what type of glue to use, putting stainless steel parts on plastic. I started with a basic hot melt glue gun and was very pleased. It works extremely well, quickly dries, and has a certain ability to pry off the the parts and do over if there's a problem. But it holds the parts on really well so I went that route. The result is not as great as a high end replica, but I think having real steel parts instead of painted plastic looks better.
