Finally arrived. Got the other end cap off, in two pieces. The first end cap had glue evenly all around the edges, and the one that broke had all the glue in one spot. Grrr. I'll leave it to the body shop to decide how to glue/epoxy it back together. I'll probably keep the AMG badge and ditch the star.
Best part is I only paid $140 with shipping. Christmas came early.
