I'm thinking its and M8 x 1.25

 

[duneracerweston]

M6x1 I do believe

Pull the suckers out and tap in some m8-1.25 and never break another ever

Weston is right on both accounts. I just drilled and taped mine to M8 before sending it out for porting. Just get a bottom tap for it or make your own. Don't forget to use lube, and do it a little at a time. Blow the hole out EVERY time you remove the tap.
