Gary,
I pulled my original kick panels out of storage to take a look at them. They are from my 65 Dearborn convertible with the 16A build date.
Was wondering why they didn't look like yours on the top edge; turns out that mine appear to have been cut at the top with a blade and straightedge. Not really clear from the picture but there are subtle gouges, flashing and an irregular edge (not perfectly straight). Never noticed it before.
Makes me wonder if they were supposed to be trimmed as part of the finishing process, and yours never were. If so, that makes them interesting if not rare, and something that wouldn't be duplicated by a reproduction.
Can anyone else confirm?
Ed.
