I have to say that I spread the rear triangle on my nishiki international and there is an obvious bend on the drive side seatstay just below the bridge. I also say a beautiful old phillips, same thing. While this is probably not such a big deal, if you were to do it to a more collectible Italian frame I would think that you instantly lost your resale value if you got that noticeable bend. There are lots of lugged frames out there with 128 o 130mm spacing though.
