Shin - you're my hero - thanks for all the pics - this is very helpful and that's what most of us are looking for when trying to attempt these things!!
I actually purchased a Hot Knife soldering pen from Ebay the other day because I've been thinking about going this route for my retrofit - so I may want to consider the other tips to help me put everything back together.
And big thanks for Craigsfocus for breaking into this and cracking the can open!! :D
