rattle in the rear

[rogershelden]

hi agian everyone

here's one that no mechanic has been able to find since I've purchased the car.

68 coupe

to this day every time I drive over a speed bump or any other bump, there is a rattle under the rear of the car like something is hanging loose.
I've taken it to a number of garages and even up on the rack, they can't find a thing. They'll even take it for a drive and they hear exactly the same thing I've alway heard, that rattle.

Sound familiar?

Any help would again be appreciated.

Roger
