Sorry Junk for lack of clarification,

All of these combination are not allowing for shifting to the lowest chainring without a rubbing the cranks. Most or more modern front der. are beveled or indented to assist in the shifting. The problem as diagnosised by my LBS has something to with the crank design which is some what retro Sugino and more modern Shimano. I have been running into this fairly often recently when I mix and match parts - even those of similar era's - for example a 1985 Miyata Valley Runner and some beautiful AT cranks - frame was not not indented enough for cranks - conclusion after 3 bottom brackets. Or another recent conversion of a Ultegra triple on a 69 Paramount - and the combination of front der a 8-9 Campy Racing Triple which works great. When mixing parts and era of parts "brands" it's alot of trial and error - and all those pesky hard to find and at times expensive parts.
