How bad is this? ( Clutch Drum )

It's really difficult to tell in the picture you posted where the damage is because the pix is huge. Is it where the seal rides? If so that is bad and it probably won't seal right. I'd replace the drum. How many clutch discs does that drum have ? I have one or two extra drums that I saved that are good I'd sell resonable. What year is yours? That makes a difference because of the width of the bushing. Another thing, how many clutch discs does your drum have? Where are you located? Only worry about answering these last questions if you think you need a drum. Tracy
