Hi there,
To get the bolt back in you would need to loosen the lower bolt on the shock absorber. This will remove the tension from the spring and allow you to move the arm around a bit. If the bolt is damaged you need to mark the swing arm bracket(To keep the alignment specs) and then loosen the lower 3 nuts on the underside of the bracket. The bracket will then swing out and you will be able to replace the bolt.
The car under goes 2 seperate PDI's, and this should have been checked at both of them. If you need a better explanation please give the shop a call and we will be able to give a better verbal explanation.
