[datsun280z]

Thank you all for the info and the great mood.
I took a ride yesterday with a friend , we believe the noises are between
the chassic to the body.
It's like a "BOOM" when you drive over a bump..
What connects the chassis to the body ?
Where can i look under the car to find a direction ?
Sorry for my simple questions. some of u are probably smiling..
Thx !!
