Welcome to the Phorum, Sparkydave. It sounds like you have a great project. When asking for help on a specific radio it is always helpful to post a schematic so the members here can help. If you are still looking for more info, I suggest you look over this site, especially the knowledge base. You'll be able to get a lot of info in your model as well as links to get you the needed info and parts.
Have fun!
