I read the searches, thanks sixto, did not reveal about the rear seat frames once removed.

Johnhef, I think your right the bases may be different. I think I need to look for models without the reclining feature. Looking at photos of cars for sale, the headrest arms have a bend like in the W124s so my straight ones will not work. I wonder which models did not have the rear seat reclining feature? Maybe the 420 SELS? SEs? Looking for 1989-1991 W126 style with the newer style horizontal leather pattern.

Thanks for the replys!
