There has been a lot of debate as to whether or not the aerocoupe cars used the same glass as the greenhouse
Caprice's from '77-'79 I think, and while it's similar, it's not the same. The G-body version is longer and the
B-body version is more symetrical in terms of height and length.
Look close guys. The first few pics are photochopped to include the seam for the trunk, in the last few, you can see it's not there and that the glass is just sitting on the back, so doesn't appear to have been done, yet...
And I love it! Who cares if it's an original GN? Between '86 and '87, they built over 35,000 turbo Buicks, so I'm sorry, but it's not like they're that rare of a car, even these days. I've wanted to build an aerocoupe Olds for sometime now, and somebody made a pic the other day, and now I want to do it even more!
You've got your work cut out for you, so get to work!
