Vent window shaft sheared off

[87Skier]

Hi all,

I'm trying to rebuild my vent windows with new seals. The driver side window has always been a bear to open and close, requiring two hands just to do it.

I got it apart and found the shaft sheared right at the vent window frame.

I'm tempted to have a go at repairing it myself, but I'm sure what metal the vent window frame is. It is the bright finish, so stainless or chrome, but I'm unsure which. I'm also unsure of how it was original held together, since the shaft is regular steel.

Can anyone shed some light on how these were made, what they are made of, and if/how they repaired there own?

Thanks!
