1964(?) Avanti R-4344 - May 2018

The serial number indicates a 63 model. The square headlights are definitly not a 63 feature. The body tag (RQ-2012) does NOT have the "63RQ-" preamble, which was usually applied after body #3100, under a factory directive. This was to separate the 64 models and beyond from any 63 association, so there's a something else going on here.
