Installing the TT forces the engine to move only on the vertical plane. As you know, the Dyna frame is a tight fit for the big twin. What they are telling you to measure is the distance of the rocker boxes to the bottom of the gas tank on the front cylinder and the rocker box to frame distance of the rear cylinder.
That adjustment bolt on the front mount, from what I can tell, is to give you the ability to stop the vertical/rearward travel of the top of the engine before it hits either the bottom of the fuel tank or the frame where it curves downward from the backbone to the cradle.
Now if it does touch the frame/tank you will know by the scars on the rocker boxes or a dent in your tank or paint chipped off the frame wherever the two contacted.
As to exactly where that measurement is to be taken; where you see the smallest gap.
I hope I have correctly cleared the mystery of the stop adjustment, if not, I hope someone does a better job than I.

Looks like I have about a half inch clearance (w/o true-track installed) before I would hit any part of the frame. Gas tank won't be a problem because of the 2" lift I have.
All I need now is some warm weather to do the install.

It may be that even with the adjustment bolt backed all the way down that the engine will not contact the frame or the tank but obviously you aren't going to be able to look and see if it's touching under full throttle acceleration from first gear, when the engine mounts are under their heaviest torque load. Now if it does touch the frame/tank you will know by the scars on the rocker boxes or a dent in your tank or paint chipped off the frame wherever the two contacted.
