Stripped Threads In Arb End Plate Hole - Help!

[macaroni 17 1 Cars]

I tried to replace the rear arb with a thicker one but, despite the arb I was sent being wrong, I have stripped the threads on one of the holes that the bolt that locks the end plate goes in.

 

I have tapped it once with the same M8 x 1.25 thread, but the inner threads are gone.

 

Is my only hope to drill and tap the trailing arm to an M10 size, or has anyone got a better idea?

 

Any help gratefully received.

m10 or even 12 is your only hope, or a helicoil back to M8

both my rear arb bolts are m10 its not a big issue, ive found this happens when using thicker arb's.
