Sig 556 swat patrol trunion work or replacement

Hi everyone,

Recently, the component (trunion) that the Allen screw connects the folding stock to the rear of my 556 gun assembly had the threading stripped and I need serious help finding a replacement component. Any help finding where I can get a replacement part or suggestions including roasting is welcome.

background: I took the existing folding stock off to replace with new one. I tried to secure the Allen headed screw in what I believe is the trunion and it got too stuck and pulled both out when I tried taking it out of the back of the receiver.

 

Is there enough metal to just insert a helicoil?
