Well a 93 500SE is a W140 and your SDL is a w126 so none of it will be a direct fit. I have seen w140 seats in a w126 coupe before so I know that they will physically fit. However I would imagine some sort of custom mounting rails would be required as well as some custom wiring to make the power seats work correctly. The switch panel for the seat may also not fit in the w126 door card in the stock location.

The centre console I would imagine won't fit... but I don't know for sure.
