Need Help With a GST Rotary Valve

[airbiscuit]

Does anybody know how to re-assemble the rotary valve without the two indent balls falling out? It is killing me. Here is a picture with the springs. The balls are supposed to stay on the springs somehow while you insert the indent plate. Asking for a friend.

Try a little dab of grease to hold them in place
