Sheared Key 1973 CB450

Yesterday, I pulled a bonehead move with the best of intentions. I wanted to replace the screws which hold in my points from flatheads to allen screws. Unfortunately, the new screws were slightly too long and unbeknown to me, the new screws grabbed onto the points advancer and trouble ensued. The points advancer sheared the key that keeps the point advancer in sync with that cam.

Rut roh.

I was able to take everything apart and get the nub of the key out and replace with a new one but the problem is that there is a little bit of wiggle now. My questions are if this wiggle is going to make it impossible to set my timing correctly and if so, what's the name of that cam specifically in case I have to replace it, I know the correct name.

Thanks in advance!
