FlipPac lift arm repair?

I bought my FlipPac in 2013, used. This weekend while lifting it, it broke right where the lift arm enters the lid, metal fatigue. I would be grateful for any repair suggestions. Photos attached.

 

Definitely not a zip tie repaire.
if it's aluminum, you will need a tig welder. They need grind off all the junk on the shell and replace the whole bracket.
Aluminum, fiberglass or steel?

 

steel, strongly magnetic though color looks aluminum.

 

Needs to be grinded down and welded back.
Plus, look at this thread, it may have a few ideas about replacement parts.
