How do I remove the diverter stem from a model 308 sayco/briggs 3 handle shower faucet?

How do I remove the diverter stem from a model 308 sayco/briggs 3 handle shower faucet? I am able to get the stem loose and it will come out approx 1/4 inch but it then seems to be catching on something. When I push it in and then try to pull it out I can hear (ting metal on metal sound) it hitting/catching on something that is keeping it from coming the rest of the way out. What am I missing. I was able to remove the hot and cold water stems with no problem.

This is a link to a picture of the faucet:

Thank you in advance for any help,
