Re-attaching rear bumper apron
 

Hi,
The black rubber was coming off the bumper...so I bought a new plastic
piece..my neighbor managed to rip the old out and replace with the new
and reattach the rubber. But on the End where it goes under the apron,
the apron is old and came off. He's having a hard time figuring how to
re-attach the apron. It is old and I need a new one, but the end of the
rubber is not really anchored strongly. Basically I need to know how to
reattach the rear right apron...I haven't found any youtube videos on
this...
Thanks

Is your car a 1982-85 300D? I just dealt with that on the front of my 1985. At the rear, I just swapped the bumper and didn't look close at the rubber apron, but recall it attaches similar to the front, with a separate steel backer sheet-metal part which attaches to the body with studs and nuts. I think you will need to remove the rear bumper, which isn't hard. Six 17 mm hex nuts as I recall, with ample room to swing a wrench. Then just wiggle it out. Then you should be able to get at the steel backer. Might need to derust and repaint it.

BTW, that apron design is a bit of a kludge for the U.S. market. At the time, safety rules required a bumper which could handle ~15 mph impact into a brick wall with no body damage. That is why the bumpers protrude and have 1-use shock absorbers. You see the same on all 1980's cars, some quite ugly on British sports cars. U.S. owners pay a lot to get the sleeker Euro bumpers. Ditto for the headlights with the plastic "doors" for U.S. market.
