Due to the curvature or radius of the bubble there might be a difference between the two emblems.
www.manciniracing.com has exact Chrysler Emblems that even have the part number on them. On the 440SixPack emblem the original emblem on N-96 Shaker bubbles had a slight 'Taper' to it. The re-pops from mancini include this important feature. On N-96 equipped Challengers the parts are either right or not. Dont settle for anything less cause everyone will focus on it, it's hard not too!
