without knowing how far out it is i wouldnt be able to say.

perhaps the best thing o do is go down to whoever will do the wheel alignment, tell them whats been done and that it needs a 4 wheel alignment and ask if after its done it needs the adjuster bolts (or arms) if they will fit and adjust them for just the fitting fee or at a reduced rate.

then you don't need to buy them until you know if you need them and which ones.

what size wheels and tyres are they btw?
