...from looking at th '94 E320 Coupe's rear seat pockets- - they are not the same as those in the '94 E500...not even close

a good upholstery shop should be able to spray some glue on there and wrap them in black leather for you...

also- from memory- I believe someone here was offering to sell you an entire black leather 124.036 interior> perhaps the pockets can be bought separately?

hope this helps
