Do you have one side to measure from?
BTW holes for the V8 on the fender are not the same driver's to pass side.
The leading edge of the V or the 8 is the same distance from the front of the fender, which makes the he's slightly different.
The GT fender badge holes are the same pass to drivers side.
The large hole for fender top turn signal is large and there is not a lot of room for error.
I have some of the hole locations but it would take some time to find.
There was a FABO member who had an OEM GT with the trim off recently, if it is still that way maybe he would make a detailed sketch of all the holes, dia, locations, count etc.
The passenger side of my dart is unmolested, but all the trim is on.
