One thing I noticed that I do not have in my 1983 240D is rear head restraints.

I was looking at the EPC for my car the other night and I noticed that there was an option for rear head restraints available.

Anyone out there know a way I can get hold of a set (in Palomino leather)? And what does it take to install them - pull the rear seat backrest and install the hardware?

Or another thing I have heard is that W124s had head restraints and the backrests are interchangeable with a W123.

Any suggestions?
