HI all

We have a few of these in the field I there's a problem.

The machine uses a slider to move the colour drums away from the belt during black and white copying and printing.
When the slider on the left wears it causes a colour drum to drop on the belt and cause a smudge. The part is shown in the picture with no part number, does anyone have it or know of a decent bodge job?
