I just converted my ’65 front drums to SSB disc’s (non-power). They look and work pretty nice. Question for others that have made this conversion, I used the existing M/C pushrod as called out. However, the pedal now sits lower (I like the height) but the return bumper no longer rests on the pedal support causing the pedal to “rattle” slightly. The bumper appears to be fixed to pedal arm. Has anyone else experienced this?
