What size torx is primary bolt?

[2005 1m]

Biggest I have is T55 and I know I need bigger than that! Any help?

Also, what is the torque spec on the secondary bolt? Thanks!

If you're talking 2010 or newer M8, my 2010 primary clutch takes a T60 and I believe it is 55# torque but better double check that torque. The secondary clutch torque I don't know, I just snug it up.
