Allan; if it were me, I'd take it to a good repair shop and get their advice. In fact, I'd probably have them do it. If thats not your choice, look up Stewart Macdonald on the web(sorry,I don't have their address) They not only have the supplys that you will need, they also have how-to phamplets and books.

ps it may be Mcdonald. I don't recall just now
