I have never measured the openings of the "egg" crate rectangles Standard vs. RS, but I would bet they are the same. My opinion again is that the Z should be split by the third vertical, but the judges in the Legend class deducted points saying it should be centered on the second vertical but I have not seen any of them defend that position or show any other supporting material other then what is pictured in Jerry Mac's book. Again not that I am correct but just from a gut feeling. One thing you will notice is that the headlights on the Standard grill are closer together versus the RS headlights and I think that might play into some folks thinking it should be on the second, but if you go to my original post the picture from 1969 is very compelling. Plus it just looks "right" again, my opinion. Jimmy to make certain your emblem is on the vertical correctly make sure the guides on the back of the emblem are split by the vertical and not to the right or left, if you've had the emblem off and looked at the back of it you'll know what I'm referring too.
