I know it`s a long shot but I am in need of 2 ZB Changer fingers because the allen screw adjusters just came away from the end plate when I tried to tune the steel

so i removed the changer fingers and 2 of them had snapped of on the changer threaded adjusters ,I can repair and make the Allen adjuster tuners if I need to, but I thought I would try and replace them if I can find some.
Thanks Jimmy.
