I will give you a hint of what I have done on my Mach1, although not the Bullitt in actual shifter geometry and how it functions, since the Mach1 is mounted to the Transmission directly and the Bullitt has external rails going up to the tranny, it still may give you some insight.
I used the Pro 5.0 and mounted up a Hurst stick that I had shortened and redrilled the mounting holes at an angle so the shifter was positioned like I preferred. I could have used the factory shift lever stick also but I wanted the real old school look, a place to mount my Hurst Roll Control and the solid feel the Pro 5.0 provided by the positive stop bolts. The Hurst for the Mach1 still had the stop bolts for the Mach1 but to me the quality wasn’t as good as the Pro 5.0.
The newer ‘05 and up Mustang Hurst Shifters do not have the stop bolts so if you want that feel then I do suggest the Pro 5.0 and more than likely you could use the stock shifter with it. The throw will be shorter than the stock unit with the Pro 5.0 so the end result will be the travel towards the dash will be less. But on the other hand, you may have to modify another stick lever to get exactly what you want for your reach like I did. You could not do that with the Shifter lever on the MGW but it does have multiple positions you can use to get a position that you may be happy with.
