I wish to report a possible variation or error on placement of the GTA emblem and measurement in the mockup drawing posted in Reply #2.
Two early GTA cars have now been measured as well as many photographs viewed (without measurement of course) but placement in the previous Reply #2 image, indicates that the Rear Edge of the GTA emblem measures 5-3/4" (inches) from the rear edge of the fender however, at least on the two recently checked, the two both measure the same 5-3/4", but to the rear HOLE (on center) of the GTA emblem mounting post, not to the edge of the emblem itself.
I know this thread is about stripes and the good news is that Vendors like NPD now carry the stripes we began discussing in this thread (perhaps as a result of this thread) but I thought it would be best to try and point out the variance or error of the measurements posted earlier.
Attached is a modification based upon recent measurements of two GTA'S, one early November and one Mid-December 66.
