Thanks for the info. I am hoping to find something with some kind of measurements for the holes just so I know they are in the right place Thanks again Dave
I'm in the same boat.
I have a 383 FOUR BARREL emblem and G T S letters coming
I have measured from a buddies real GTS the spacing to the center of the T to the rear edge of the fender along the body line and I get 6.5 to 6.6 (this in in CAD based off scaled photos)
Drivers side - the dimension of 6.584 is what it came out to based on the photo being scales (locked aspect ratio) to the size of the business card
The photo I took on the passenger side was not the best ( skewed and the tape covers the width of the card) BUT without any manipulation (I scaled the photo, placed the lines and then took the measurement) it came out to the same dimension to 3 decimal places
and it does seem to be ALMOST aligned under the antenna
NOW some things that concern me about this particular placement is the T seems to be lower than the top of the G and S and the 383 Four Barrel seems to be closer to the Letters than in the other photos posted
red line shows the top of the T lower
Blue Line shows the angle of the G and T are really close but the S seems off?
The spacing of the GTS seems about the same as the other photos
