I dropped the hinge bolts inside the body, any help retrieving them?

Did any of you ever notice all the junk and parts that fall out of a car when turned upside down on a rotisserie.
I work at a restoration shop. We have an olds convertible that was on a rotisserie. Every time we rotated that car more money would fall out. That car was paying out like a slot machine for a few weeks.

On the original subject, I dropped bolts in in the same area on my cuda 3 or 4 times in a row. Its a black hole in there, just eats hardware. I finally got it out but it was not easy.
