Yep i checked the fitting guide and there is only one way they can fit with the adjusters on the top.
Ride height is 355ish and the castor rods are standard.
They are offset like the standard arms, you can see that the top pic is the RHS and the second pic is the LHS. In the LHS pic you can see the offset bit in the top right of the pic
Yep it was done on an alignment machine. It may have slipped though if they weren't done up tight enough - It's getting towed to the workshop tomorrow so hopefully can sort it out.
Many thanks everyone for the replies, keep them coming!
