The one with the felt should not slip on the axle. The way I'd usually solve this when a nylon part isn't split to bits is to clean of any lubricant, lightly scratch the axis where the part should fit. Slide it into place removing any other part if possible, double check position, apply a drop of super-glue with the tip of a small flat screwdriver so that it fills the crack by capilaity. Not the neatest approach effective in most cases.
If take-up still isn't working after trying to adjust the clutch force, suspect that maybe the original spring was lost at one point.
