You have to remove the reel seat and handle...probably have to soften the glue by boiling it, remove the wraps and guides, clean the blank well with something strong enough to clean it well but not remove the finish...now you'll have a blank to build the new rod on.

You'll have to experiment with guide placement and determine the size depending on what size line you decide the rod might cast....you might have to tape up some guides and throw a few size lines to decide the weight of the rod. Hopefuly your local shop has tip-tops so you can simply bring the rod in a try a few sizes.
