Now I know why 904 was having issues
Yes that drum comes with a new bushing.
This is the part I'm talking about:
It goes in place of the big wound spring that's wound the opposite way of release, for when your wailing on it. I 'believe' you can install 5 .086 thick clutch/steels in it as well. It goes behind the pressure plate in the direct drum (the one that you replaced because the band burned it up).
