Default Cracked headlight housing support

Hey everyone!

A while back I noticed a crack in one of the forward 'arms' on my driver's side headlight housing support bracket. I knew it was something I should address at some point, but I was busy and didn't get around to it. Today I pulled the car out for a spring start up, and I noticed the driver's side headlight housing was doing a good amount of shaking at idle (in both the closed and open position). It's not shaking like it's going to fall off, but definitely more than normal and more than the passenger's side. It's definitely from the lack of support on one side of the housing, and I need to fix it before the vibration from shaking and added stress on the other side causes more damage.

Just curious to see if anyone else has run into this (obviously someone has) and what your fix was (aside from replacing the support). I'm thinking some JB-weld on the crack, and then attaching a metal strap to reinforce the crack.

I've attached some pictures below:

That's a bad spot to try to fix, Yes JB weld and rivet some piece of flat bar will work (for a while). Best bet it to replace it.

Weld it! Mine were also cracked on the top side where they bolt to the "header bar".
I took it to a specialist welder and he welded it very nicely.

Bingo. The supports are pot metal, but a first class welder can make the repair.

Be aware, on my 71 the metal from which they were made was a mixture of iron and aluminum and it wasn't easy to weld them.
And that is why they get coroded also. Because of the chemical reaction between iron and aluminum.
But a good welder will know how to do it.

Luckily I have a buddy that is the welder at a really high end Corvette restoration shop that is 5mins from my house. He welded my broken side pipe mount tab, and my broken rear strut rod bracket last spring. He's a real good welder. I just messaged him and told him it's time for his annual weld my broken **** session! lol I'll update you guys with how it goes once I get it over to him.
