Scratch the D-5NT and hope for the D-5NA which was basically a P-51B with a bubble canopy and two more guns.

The P-51D-10NA had the dorsal fin installed after it was first used on the ETF-51D which was a P-51D-5NA modified for full carrier operations.

The P-51D-20NA was the 10NA with the new K-14 gyroscopic "ace-maker" gunsight.

The P-51D-25NA introduced rocket stubs. The P-51D-30NA was pretty much the same thing...

You're right about what NA and NT mean and the Dallas canopy was installed on some of the NT Mustangs. The Dallas canopy was just an unintended variation made by different batch runs of the canopies, but most people think that it was special for the P-51K.

The P-51K was a P-51D with an Aeroproduts propellor that hindered performance in the early versions and slightly helped in the later versions due to the balance of the prop that was fixed over time. The P-51K-1NT was the equivalent of the P-51D-15NA, the P-51K-5NT of the P-51D-20NA, the P-51K-10NT of the P-51D-25NA, the P-51K-15NT of the P-51D-30NA.
