Generation IV External Engine - Sheared the a/c tensioner bolt, replacement suggestions?

I sheared the a/c tensioner bolt (bolt that mates the tensioner assembly to the a/c compressor bracket) off today. GM only has the bolt available w/ purchase of a new tensioner, which is $30 more than an aftermarket replacement.

Can anyone provide the specs of the bolt? I'll see if I can source it locally before I buy a $30 GM bolt

ask gm what the bolt pattern is and thenth is ( to make sure it the right one lol) i have done it a couple times to get the mesurement

I got the specs of the bolt, but can't get the rest of it out. In case all else fails and I replace the bracket, can I use an a/c bracket from any LS car engine or are the brackets GTO specific?

This happened to me like 8 years ago. The a/c tech at the dealership had a kit just for that. He drilled the hole out, screwed a new threaded sleeve in and I believe it came with a new bolt too. 15 minute fix.

Its been good for 8 years.

edit: oh, you're not stripped.
