This may not be good news, I'm afraid. I had an elderly CDI furler on my Morgan. It fell apart one day while I was raising the genoa and the jointing pieces which hold the foil sections together came out and fell into the sea (not all of them - but from two sections). I just could not find replacements and eventually replaced a the furler with a new plastic section one from CDI. I guess my point is that spares fro elderly furlers are often difficult to come by, unless you can spend the time to locate them on the used market. Have you tried advertising?
Leith (rhymes with teeth) is the port of the City of Edinburgh in Scotland. A Leither is someone who comes from that area.
I must go down to the sea again, to the lonely sea and the sky - I left my shoes and socks there, I wonder if they're dry?
