I installed the shocks about 6 months ago and now I'm hearing a low level noise from the rear and then found the problem crossed threaded one of the two at the top, not the bolt the hole

 

I now put everything back but did not got the bolt size. I had a quick look online and saying it M10.75 do you know if that right ??

 

Guess I got to Helicoil insert this weekend which I do have if its M10

search for info by part code
