Odd that there's not a BJD General on /toy/. I could really use some advice.

Thanks to my Trumpbucks, I bought a Dollfie Dream Sister off eBay. This is my first DD I've bought in years. I have 4 already. She's used, but untouched as far as face ups and blushing goes. There's several flaws that the seller noted, but I think I can fix those. But what I wasn't expecting was the neck post snapped off. Clearly it broke during shipping. I've already wrote an angry (yet politely worded) letter to the eBay seller.

At least it's a clean break. I'm guessing I can fix the neck post with some heavy duty glue and a small piece of wire or metal pin in that center hole. But what type of glue should I get? I need something that's strong and can take the stress of a moving head joint. It also needs to bond to plastic & metal.
