Lets chat a bit about that drawing. It looks like the detail of "View in Circle Z" has dimensions on it (the numbers in the ovals, i.e. 128.4 as the start point). I am guessing that there is a datum somewhere on the car and you measure 128.4 inches from the datum to get starting point. If so, it looks like the first thin strip is about 1/4" and the space is about 1/4". I say about since the difference to the larger solid part is 0.45", which is just under 1/2". So where am I going wiht this? Well, where is the datum? Is it the front edge of the fender? Is it the CG of the car (which would make sense since 128 inces is about 10 feet, the overall length of the car is about 17 feet, but it is front heavy shifting CG to the front).
Now if all that makes sense, when I was the Hamtramck site, there is an engineering drawing for the placement of the R/T emblems. That drawing did not seem to indicate how far, front to back, from the datum, the emblems should be placed. IIRC, it did have the distances from the body line vor up/down measurements. Anyway, I am just trying to make sense of these drawings. If I am confused (Masters in engineering), I can imagine how the line workers felt when the first cars came down the line.
