These top two photos from Jim Krausmann's 300C


300C with replaced roof rail w/strip but original dongle thing on the end. Looks like the '58 has different dongle connection and might have an additional inner strip along the windlace (See Below).



Here are a couple detail pictures from my untouched, factory original
58 Windsor 2dr hardtop that had 30K original miles on it
when these were taken. Both are taken from the passenger's side.
Hope it helps.
