Stage 1: 25nm or 18lbf ft
Stage 2: 55nm or 40lbf ft
Stage 3: Turn 90 Degrees
Stage 4: Turn 90 Degrees

Not sure if you know how to do these, but you have to tighten ALL bolts in a numbered sequence to Stage 1, then Stage 2, etc, etc...

Do you know the sequence they have to be tightened? Can scan it and post it up if ya need it?
