Score! I just picked these up from a Euro W116 in the junkyard today.
Now I just hope rear headrest brackets from a '79 W116 fit in a '79 W123 with a '85 W123 rear seat spring set.
Any tips for re-skinning the cushions? I realized the 'rear' headrests I had are just front ones, so I need to put the blue covers from them on to these.
