[W126 Coupe] AMG rear bumper lip

[Mike Kelly]

As I just wrote, my '89 560SEC is in the body shop being 'tricked up'.
I managed to find a new AMG rear spoiler and front lip but I haven't yet got
a rear lip.
I bought an Erebuni [or something like that] but I don't like it and won't
be using it, so I'm after an AMG rear lip that will fit my coupe.
Any suggestions where I might buy one?
