I think the vent thing is just going to keep you up at night! I did find one interesting fact... the 78' Intriguer (which is essentially the same sled) has the hood vents facing from left to right! The Intriguer hood had the headlight on top of the hood instead of integrated like the Drifter. I dunno. Maybe the assembly crew cut the holes thinking the sled was an Intriguer! lol
. In any event, it is interesting, but I suspect just a factory "glitch".
NOW... if you had a Drifter that had a factory installed 530... now THAT would be something else!
