Hello to all!

I currently have a 1981 300td station wagon. I recently bought a DOG NET/CARGO NET which I want to install iinto the vehicle. My problem is that i heard US versions don't have the bracket in which to connect the net. I have asked quite a number of MB aftermarket shops and no one seems to know how and where those hooks are located and how they look.

Can anyone please help me with these brackets? All I need are pictures and diagrams so that I can, if it leaves me no choice, have them fabricated.

Hoping for anyone's help.

Thanks.
