This product is a reproduction Commodore 128D / 128DCR Floppy Drive Lever for the european PAL (plastic) 128D with the built in handle and North American metal 128DCR.

This is a direct replacements for a broken lever. Simply press them onto the shaft and you're off the the races. In my experience, the originals typically fail by splitting as over the years the strain (and age) takes it's toll. Because the shaft is recessed into the front of the case, without a replacement, it pretty much renders the drive un-usable. 

Bring those old drives back into service with these super strong PLA, 3D printed door levers.
