Here is a chart of shear strength of different metals:
You can see that very low carbon steels and brass (other than cold worked brass) have similar shear values. Since I had no way of knowing what kind of steel pin was in the drive (one had a roll pin => very hard!) and I was not about to pay LeBlond prices for replacement parts, I just used brass. I annealed it to be sure it would be soft and called it good.
