My father has an '07 S550 and would like to replace both of the front door sill pieces that say "Mercedes Benz" pictured here-



Can anyone recommend a website and perhaps help me out with part numbers?

I'm assuming I want the "inner" sill as opposed to the "outer" sill?

Thank you.

 

Left 2216800135 + color code, right 0235 - PM VIN I will supply full # with color code to match interior.

 

PM sent. Thanks for the help.
