Size of the threaded inserts for an aux fuse panel in the engine bay?

I read it before in the 3rd gen forum, didn't write it down and now I can't find it, even with the search....the 2 OEM threaded inserts on the inside of the the driver's side top part of the inner fender which can be used to retain an aux fuse panel - what size thread are they? I don't have any correct size metric bolts to check them.....and if anyone here has used them, any idea how long of a bolt you used to retain an aux fuse panel? Greatly appreciate the help - have a Paranoid panel due in, and was hoping to grab hardware while out at lunch today - Bill in MA

I know I could reach out to them, but was hoping there is someone here that has insight to what they used on their install - Thanks again!

 

I think they are m8, but not 100%. They are the same thread as the bolts that hole the behind seat panels on.

 

Thanks for the response - I think I found it in one of the mods threads, as well - M8x1.25 - I may pick up a few different lengths as lunch, but only if it stops pouring rain - Thanks Bill in MA
