Motor Mount Bracket to Engine Block bolt size

Anyone know the Motor mount bracket to engine block bolt size/grade?

I am currently installing my Brown Dog 1" MML and upon removing the bracket one of the bolt threads is toast. Already verified the hole in the block is clean with another good bolt, but not sure what size.

I looked on a few threads but couldnt find anything.

Thanks! :2thumbsup:
