That trade list doesn't work that well. Part it out and sell the frame. Or maybe just sell the RD and replace it with a less expensive campy RD to sell the bike complete since it has all the nice pantographed parts. It's my size,

.
But seriously, I wouldn't waste a lot of time restoring a bike that wasn't my size which is too bad because this is a beautiful bike.
Will a taller stem and seatpost solve the problem? It would be a drag to lose that pantographed seatpost but if that lets you ride the bike, it may be worth your while. Nitto has a good selection of tall stems.
