You're right on the Buicks John....I was looking at '64 Wildcat trim myself and it appears close or may be even the same. . Here's a link if it works. .

The 4 pieces in a row reminded me of '58 Bonnevilles but looking at pics it's different....looked closer at '63 Impala fender trim but different too. .
Any Buick experts here w/ a '64 Wildcat in their garage? .
