tail light lens help

you are referring to the d shaped chrome piece, no studs left on it right? I would use either auto plastic emblem glue or maybe superglue.. clean all parts good, let the glue tack up some, then attach the chrome and carefully tape it down with some masking tape to hold it till it dries. ( yes keep the take away from the glue!!) HA
i'm like you except I am missing the d shaped trim all together!!!
