What headers work, and what don't?

Crackedback -- I beg to differ... if the 73 is the same as the 67 and 68 and 70 and 72 THEN my statement that the 73 is the widest A body MADE is exactly true....what can be included is the entire range....67 thru 74 they are indeed the widest A body's made....73 just happens to be INCLUDED in that range. SO how exactly is that "flat wrong?" Would you prefer that I might have said 73 is among the widest? yet is it not in fact the widest group? as is the 70 and the 72 and the 67?..... picky picky
