CTC-9 Convergence Question

[mstaton]

I tried many times to do the convergence on my 1959 CTC-9. It has a 21FBP22 CRT. The convergence is perfect except the left and right vertical. the red is off. i just found out this is supposed to have some magnets attached to the crt like the pic I found on VK. Look like little steel pins. Any suggestions? Pic of what should be there attached and also an actual pic of the Tv working but its hard to tell the convergence is off in the pic.
