I have had a set of the early repro knockoffs on my 65 since the early 80's. They do not have the pins and they do not move if you put them on correctly. 8 spins and a few good blows with a real lead hammer and your good to go. I put little crayon marks on the outer rim, lined up with the 3 spinner points. This allows me to check at a glance if they have moved. It also saves your hammer from needless damage. They have never moved.

Drill them and add a pin or just make sure you whack the bejesus out of the spinner with the mallet?
Adding the pins requires precise machining of slots through the threads on both the adapter and spinner; not worth the effort. Just get a "Mother-Thumper" lead hammer and beat hell out of them, use a little anti-seize on the threads and conical mating surface, mark them for a visual check, and drive on.
I safety-wired the Halibrands on my Grand Sport (from the end of the ear at 2 o'clock to the hole in the wheel at 3 o'clock) with a little slack for visual checks, drove hell out of it, never had one loosen.
