I can't see from the part number what bit you are referring to but is it the bit that the cables bolt too?
if so, I made one out of the pins that you use on axle stands.
This is the part, iv ordered new cables, and i had to source a new handbrake lever part,
Im hoping its the correct one, as iv seen others with a bent runner type thingat bottom and mine dosent have that :/

I also have part number 33 with a bit of 31 cut off and left on it,
