This should be an easy one.

I am trying to remove the front drivers seat out of my 1982 Mercedes Benz Turbo Diesel. There are 4 bolts very similarly to any other vehicle but the two bolts in the back are very difficult to put a wrench on and seemingly impossible to put a socket on. What can I do to remove this seat? I really appreciate any help or solutions you can give me. It seems like it would require a special tool, does it?
Thanks a Million, I am super glad to of found this forum and this Mercedes.
