The problem is that I don't have the W126 armrest to hand to compare to my existing W124 item. The guy selling the W126 one is in the U.K. (I'm in Ireland) and if I go ahead and buy it, to discover that it dos'nt fit, then I'm stuck with it !!! The actual fitting of the armrest is not the problem as long as it is compatable.
I tried looking at that German Website but it appears not to be operational.
Many thanks for your help.
