Hi - I have an 2008 GD3 Sport with M/T. I need some help sourcing the stud on the Engine side for the passenger-side engine mount. I accidentally overtorqued the nut (top #16 in pic) that secures the mount bracket to the engine and now the stud is spinning. Haven't taken it all back out yet, but I suspect the threads on the engine side are also ruined and need to helacoil it or something else. In some M/T diagrams the stud is listed as E-11-11 whereas A/T (shown below) has both E-11-11 & E-11-10. Does anyone know the size & thread pitch? I have never put in a helacoil so I'm a little nervous about that let alone sourcing this stud. Any suggestions or advice are greatly appreciated!

 

Size M10X1.25
When I planned for motor mount replacement I tried to break this nut loose in advance I noticed the stud was turning as well , so I tightened it back and applied WD40 to the exposed threads of the stud. After one week,the nut come out without issues and I completed the motor mount swap.
Now back to the stuff: the hole is deeper than the stud and could have some threads left. Inspect the hole and cut few more threads using tap then use the bolt of appropriate length a (saw this repair on the junk yard)
