Finally! Positive proof! This one certainly convinces me, I now see the error of my ways!

Now's my chance to own an authentic all-original Canadian Firebird, built with the rare Chev 6 (why didn't more choose this option?), the Camaro fenders - and even the original snow plow mounts (actually fairly common on the Canadian Firebirds, but most people threw them away after the first scheduled fender change)! Thanks guys!
