I can't speak for the Gen II (late '65-'68) T-bird NR I or II, but as the long-time owner/player of a '64 II - the recent Epi VP IV is the closest you'll get to a vintage "reverse" T-bird in looks and sound for a fraction of the price of an actual vintage example.
The VP definitely feels and sounds close. A Greco sounds even closer, but doesn’t feel quite the same (wider nut, shorter scale, etc.) The Greco has more low end. Both are great basses.
