Replacing Backplate Handbrake

I need to replace the "backplate handbrake" on my Cerbera. The spacer tab/stop (just above where the handbrake cable goes thru) was broken off. Has anyone already replaced that and how.

This is how it looks like:

Thanks, Peter

Hmm, I'm having difficulties in accessing the 3 hex head screws as the half-shaft is in the way.
My hope was to push the driveshaft so far back to at least get access to the 3 hex screws.
I see 2 possibilities:
a) remove the half-shaft either on the diff or axle side and then slide the axle out
b) removing the top bolt on the upright (top of pic) and tilting the upright outwards and hopefully slide out the driveshaft

Or is there another trick I don't see to access the hex-head screws ?
