I also noticed the seats were not '76 seats. But the frame is the same, so when I recover them, no worries. If I recall, the cowl tag shows my car to be firethorn interior, but I will check again when I get home.
I do love the look of the '75 seats, better than the '76. I don't know what to do with the car really, I like the idea of a factory restoration, however, I got this car to build a L/E clone, because there is no way I could ever afford a real one. Not to mention, I want a few minor upgrades, like 4 wheels disk brakes, heads/cam/intake, true dual exhaust, you know little stuff, and I for sure don't want to do that to a REAL '76 L/E.
At the same time, I don't want to be disowned by the Pontiac guys...
