1998: 65 mm
1999: 66.8 mm

Using a caliper, I measured my 99 GT factory TB bore size to be 68.5 mm. Maybe my measurement was off, but maybe not. The bore might have a taper, and it depends where you measure it. It may actually be 66.8 mm at the butterfly valve. Along similar lines, I measured the bore of my 70mm Accufab TB to be 73 mm.

The same article lists the BULLITT TB size to be twin 57 mm. It did not provide any data on the Cobra motors.
