Do these come apart other than just the screws and 1 black bushing/spacer? Ive broken down couple of shifters including some vintage campagnolo and some older shimano shifters in which BOTH had several parts within each shifter. Are these just the way the slightly newer shimano 105's were made? Im doing this because Im breaking the parts down to give them a thorough cleaning, but im having trouble breaking them down, without literally breaking them.. Thanks.



^These are the other older shimano shifters that I broke down from a Univega Nuovo Sport just for reference.
