Is it possible and how would you insert W123 (manual) seats in a W126 300SDL?

Can you still have power functions and will the back seat from a W123 fit?

I've already read other threads on this topic. Maybe someone can help me start a custom DIY. I will take pictures throughout my work, I'm in the process of restoring a 1987 300SDL.

Thank you for ALL replys and suggestions!

I think most go the other way around with the seats. The W126 seats are superior than the w123 in all aspects.

but... It could probably work. I've never seen a power seat out of a car but maybe the mounting brackets that hold all of the electronics will swap over.


but the rear bench seat will not work, IIRC the w126 is slightly wider.


question, why?

I don't know, but I sure would like to know if w124 seats would match up to a w126 seat frame.

I imagine the 124 or 123 seats can be adapted fairly easily to the 126 frame. Some of the electric motors may be in the frame. I think the back recliner is in the back of the seat though.

I agree the 126 seats are the best IF they are in good shape.

The seats I wanted to switch (manual), are in almost excellent condition and were also free.

The existing seats (w126), need to be reapostered, meaning... $$$$$
How would someone wire the manual seats?

Any ideas are greatly appreciated! Thanks!

Not to hijack the thread, but I'd be interested in hearing more about this. The seats just bolted right in without modification? I just might do this myself then, to get the powered/heated seats... Finding a good place for the switches might be difficult though.

If w126 seats will fit in a w123 frame why wouldn't w123 seats fit on a w126 seat frame? Electrics or not... I'm not worried about better quality, I just want better looking seats.

what about a w124 interior in a w123, full front and back seats? or would the back seat be the incorrect width?
