Will the originals clean up somewhat ?
ANY non original parts won't helpthe value of the bike any..
Won't hurt to post a measurement including diameter, or you end up with gold ones that are not quite right..
I still have a half bag of original Torrington nipples for Schwinn and other makes. They are from the 40,s or 50,s , but the correct long 2 flat nipples...... they sell like crazy when I put them up for sale, because they are very hard to find..
