Something living in your racecar ?

This old Chassis has been laying aroud for a few years.  Some critter took up residents in the rear clip of the chassis. I had to shorten the rear of the frame also. I cut the rear of the frame off and found a nest on both sides inside the frame rails. There are blind nuts in the frame for weight mounts that must have been how the little critters got in there.  I was just glad they were all gone by the time I got there.
