If you can find 2 bolts that are longer than the ones you use to install the lockout, grab them. The longer bolt will be easier to start threading (since the clutch springs push back pretty hard when installing the "regular" length bolts). Once you get the longer bolts started and screwed in a bit, start installing the regular length bolts, just get them started 3 or 4 threads worth, just enough to hold...remove the longer bolts, and your lockout will be in a position where you can easily put the remaining regular length bolts in, and then tighten them all accordingly, in a similar fashion to you tightening lugnuts on a wheel. I don't torque these bolts, I just tighten them until I can't tighten it anymore, lol
