These Shimano 105 friction (non-index) shifters fit pre 1985 non-square braze-on downtube bosses; set does not include cables or cable casings. Includes the boss covers as pictured and the screws are the standard M5 type. NEW old stock!
Note that these use 4.5mm attaching screws which is common to Italian style bosses, Shimano prior to 1985. Check your bosses. There are many ways to get these to work with 5mm bosses, especially if you have your OEM Shimano parts remaining from your old units.
