86, since you have a t-top and I don't they they are much more structually sound than a convertible, I would take a look at the roof and the doors.
I got rear ended once, got out, looked and saw no damage to the bumber. I let the guy go. I got home later and noticed that the door was bent and the jamb was bent. It actually broke my door hing bushings. One of my dings actually popped completely in because of the collision.
Those are just some suggestions.
