S3 rear bumps

[C43]

Hi

I am getting my car resprayed and am in the process of stipping it down. I have removed the rear bumper and rear valence as an assembly but the threaded  inserts in the rear bump for the bolts that hold the valence in place are all loose so when you try and undo the bolt the threaded insert just turns in the bumper without undoing the thread. I have used a grinder to get the head of the bolt off but I am now left with the bottom thread of the bolt stuck in the insert which just turns in the bumper but does not come out. I am thinking of pinning the insert or gluing it back in place so I can undo the last bit of thread but does anyone have any details of this insert of a better way of attacking it?

They're called jack nuts & you should be able to cut/grind them out & replace.

Perfect thanks, as you say I can just grind the head off and it will fall down into the assembly. I was thinking it was a bonded insert but then again this is an Esprit we are talking about....
