Yes, that is it..very common.
It is the top bushing ...the glue that holds the rubber insert to the bushing sleeve dries up , allowing the top eyelet to rattle like hell. By sticking a large screwdriver in between the eyelet and the mount, the rattle ceases.
If you look close , you can actually see the top of the shock moving rapidly sidways. That is the metal to metal rattle..the bushing is actually still good..it is the glue that has dried up. So, there is a very simple solution...You can replace the shock/damper or you can simply sandwich an O ring the size of the eyelet in between the eye and the mount,, Just take the top bolt out, slide the O ring in, like a washer and re-install the bolt.. The ring just takes up the side movement space of the bushing. Several here have used this tip of mine and it last for years....and cost 50 cents.
A very annoying rattle common to all the chassis that used that Tensioner/ Damper system..Later chassis used a different tensoner that did not require the shock/damper.....so it was eliminated on the late 124s..........
