Narrow T dial is correct on 105.012-66 CB.
1967 was the phase-in year for the Wide T dial, and you see both dials used on watches produced during that time.
You see many more Wide T dials on watches that were produced from mid September 1967 onwards.
The latest 105.012-66 CB that I have in my archives with a Narrow T dial was produced on October 27 1967.
All of the other ones that I have in my archives with a later production date show the Wide T dial only.
