My 96 has the usual holes above the front indicator/sidelight unit, and it appears this is approximately where one corner of the aluminium bracket that retains said unit sits. Considering the bracket also has white powdery deposits,add the presence of water and a small electric current, and this looks like differential corrosion.
Has anyone come up with a good solution for this? Before I attempt to re-invent the wheel

I forgot if the lights have a dedicated ground wire or if the ground connection is through the bolt and bracket to the steel wing.

If there is no ground wire it would be a good thing to fit one and use plastic bolts.

Unfortunately there is nothing insulating the steel bolts from the alloy light unit. This has resulted in the first broken bolt on this project. Perhaps I should replace the bolts with plated ones when refitting

On my '77 96 the bracket is steel too. The unit itself is an alloy but it sits inside a rubber boot that insulates it from the steel fender.

Thank you both.
If someone has made these aluminium brackets up at home, they have taken time and care doing so. Unfortunately they are now badly corroded.
I'm sure I have some stainless lying around somewhere, as this sounds the best solution

They should be steel and as Derek already indicated, most are rotten. I've remade a good few from random scrap metal, both mild steel and stainless.

On my '76 these U shaped retainers were steel and rusty so I remade them. Can't think why they would be made of an alloy. Any one else with alloy retainers? I can imagine someone making replacements from alloy strip because that's what was available and was easy to bend up.
