Nice looking Barracuda Zoltan. First of all, let's get rid of some myths here:
The rear glass is NOT hard to find. They are almost indestructible and most Barracuda owners have a spare in their rafters (I know I do). Most Barracuda shells you will find in a wrecking yard will have everything missing except the rear glass. They sell for about $100, don't let anyone tell you they are rare and worth $1000, that's BS. There's more rear windows out there than cars to put them in.
The first Hemi under glass was actually a 1965, which was later refitted to look like a '66, then they did up a '67 I think.
