I ran a 9mm drill through it and tapped it out for a 10mm x 1.25 socket capped stainless bolt,simply because that's what I had to hand,I used a smear of assembly paste and screwed it in.
I still haven't installed the headers as I need to change the exhaust downpipe flanges.
I just haven't had time to get it to my exhaust guy to have the pipes done.
As yet I have no comments on if it works or not.....time will tell.
