Right Hand Mirror Threads Stripped

I saw something on this recently and I can't seem to find it. In any case this mirror has left hand threads and I need to heli coil the right hand control where it goes in. Has anyone been successful at figuring thread size/ pitch and who would sell a lot for this?
Please let me know.

Thanks

The thread I started is as per below link (stripped right hand mirror / throttle side). What I think I know so far (please correct if I'm wrong):

1) Thread is M10 x 1.25
2) Confirm if it's left or right hand thread. People told me that it's left hand thread but when I checked mine, it's righthand/regular threaded (phew - now I don't have to find left hand helicoils)
3) You might have to buy the fix a thread kit. I've learnt that helicoils come with their own STI taps. Someone said you can go next size up, i.e. M12, but it hasn't worked for me. (http://www.noblefix.com/helicoil/HeliCoil-STI-Tap.html) or (http://www.walmart.com/ip/Helicoil-5543-10-Thread-Repair-Kit-M10-x-1.25/16487907)
4) the thread below, there is a guy selling brake lever bodies if you don't want to helicoil - but you'll have to re-bleed brakes.
5) Fix a thread kit is same price as labour from a shop. with the right kit and STI tap, it's quiet easy to do. I've actually repaired a blown fuse plug with a kit and it's own tap and was very easy to do.

I'm going to try it this weekend.

 

Looks like mine is actually M8 1.25 pitch left hand threads.

 

you could remove the left mirror and test size at with a nut to confirm sizes.
m8 = 8mm diameter 1.25 is threads per mm so you would have 5 threads in 4mm length

 

Now to find a vendor that has one

 

Look up, and to the right.

 

Just an FYI Len does not have these.

These guys have a kit but it would be nice to get what I need and pass it along to a few other guys to split up the cost.

 

The stock mirrors are M10x1.25. It's strange that yours are a different size. Are both sides the same?

 

I will double check
