Brackets for jump seats needed
 

I recently purchased 3rd row jump seats for my 2000 ml 430. Now I am having problems locating the brackets on the inside wheelwell that allows the seat to stow in the upright position and swing down for use. I have been to 2 MB dealers and they could not find the brackets on the schematic diagram. I called MB direct and they only dealt with dealers. Can anyone provide a contact and/or part# to obtain the brackets.
