remove it with a razor blade or sharp knife by cutting of the epoxy and binding.
take it to bcf or west gosford bait and tackle and find the right size.
buy some similar color thread/binding and some 5 minute araldite.
superglue the guide in the right position then rest the rod on a table,a small bit of super glue to keep the thread from spinning, wrap the guide tightly up and then back down,finishing with another bit of super glue. mix up your araldite,apply evenly where needed.
thats the very basic way but it works. good luck
