I repaired the power antenna on my '97 S500, but managed to lose the shiny hard plastic cover over the outside of the through-body seal. It popped loose as was sliding the end back through the seal. I thought I had it re-seated properly but I was wrong. It flew off somewhere down the road. I'm trying to find a replacement but having no luck.

Does anyone know of a source, have a part number or have one for sale?

Thanks.
