right after this post is the first time you linked to the kit.
I've installed a gmpp handling kit for someone which consisted of struts springs and mounts. Sorry for shitting in your thread..
BTW did you get that bolt out with the heat gun yet? if that didnt work try lighting a candle underneath it. last but not least pour a cup of hot chocolate and sit it next to the head of the bolt, not the threads, and it should just fall out on its own from all the heat.
