Probably. This is the across the top trunk trim piece for a 1965 Acadian Canso Sport Deluxe. It's almost
the same as the 1965 Nova SS, except it's indented to accept the Sport Deluxe emblem. A decent SD
emblem is difficult enough to find, but the trim piece with the indentation is almost impossible. Hard to imagine
why the Acadian didn't have the SD emblem on the trunk lid above the trim piece like the Nova SS. Instead,
they designed and made brand new parts for a production run of '65 SDs numbering fewer than a thousand cars.
The '65 Acadian had many more unique and costly 'one year' design elements that must have driven the bean counters
nuts. Total 1965 Acadian production (all models) was just 6198 cars.

This may explain why after 1965, the Acadian had few unique characteristics and started to take on more and more
Chevy II/Nova trim and interior features, becoming almost identical by the end of production in 1971.

the car makers just don't make trim like they used.

GM had money to burn in the 60's. Look at all the unique models that the brought out.

I had a 65 SD for about 27 years, 1986 to 2013. That piece had been slightly dinged right in the centre. I took it off and straightened it out but of course the anodizing starred on me. I was never able to find a replacement piece for the car.
