My window fell through or off track while rolling it down. After taking apart the window and motor system this part was stripped beyond repair, I cant find it online to order anywhere and I was hoping somebody could reference me a part ID or solutions if any, Thanks!!
*see photos

This part needs to be replaced

The circled area is where it goes

 

That part is not replaceable. You have to purchase the complete window regulator - (what you have in your second picture)
