Having a potential strategy to make up a small plate to fix the broken

The existing components are nice steel and roughly 1.2 mm thick, so that
seems a good starting point.

As usual, Google is not necessarily my friend.

My first thought was shim steel, but a quick search doesn't seem to go
above 0.8 mm. Not sure about galvanised mild steel such as

I assume that aluminium would be lighter and easier to work with enough
strength for this job.

I seem to remember chucking out all my spare bits of waste metal which
might have come in useful as part of the ongoing tidy and downsize. Ah,
well.

Possible candidates at 1-1.2 mm

Go round and check all the older road signs. Some of them are 2mm
aluminium. Squirt the bolts with 3 in 1 while nobody's looking and go
back in the night. Or, if you only need a small piece, have you got a
battery jigsaw?
