Roy, your car doesn’t look to me like it sits too high. Dropping the nose 2.5 inches would be a bit much, imho. To your questions:
The off-the-shelf narrowed beam is only 2 inches narrow. I think that would tuck the wheels under the fender OK but would not be as narrow as a stock TD.
I think the drop spindles put the track out a little, but not an inch. More like 3/8-inch per side. So the narrowed beam would still bring the tires under by about 5/8 per side. Two-plus inches down, though, might be trouble.
The tow bar should work. What messes up tow bar functionality is the bolt-on beam stiffeners.
