Does anyone know of a good source for 21.15" quill stems? Mine has a bit too much forward reach and a bit too low, and I am looking for an alternative. I am aware of the two that Harris Cyclery carry.

It is for a '73 World Voyageur that I am pretty darn certain is 21.15" (don't have my micrometer handy), but if someone knows otherwise, please let me know.

EDIT: OF COURSE I MEANT 21.15mm -- TOO MANY SLEEPLESS NIGHTS WITH A NEWBORN

Thanks in advance,
Chris
