Never been a big fan of the 67-68! I apreciate their sleeker style but it just isn't for me. Personally I like the 71-72 grill. It is by far my favorite. Right now I have a 72' blazer project, and a 72' suburban; and someday would like to get a 72' swb fleet Cheyenne. So no matter what it is if it is a 67-72 chevy truck my vote is for 72' as the best year.
