How To Align S Max Lower Arm

[JOHN31]

hi

i have an s max 59 reg and i have replaced the sub frame as it was bent in a accident, i think i need to align the lower arms but don't know how to do this, there must be some way of doing this because if you loosen the 2 pinch bolts on the rear of the arm, where the anti roll bar bush is the arm can be moved which moves the caster ? so how do i line it back up again ??

and just a quicky is the anti roll bar the same as a ford focus 02 reg onwards does this have an angle or height it needs to be set at ???

there are no Haynes manual out for this vehicle i wonder why ???

thanks a lot for any help you can give
