Remove Toyo Spring back?

[Atracksler]

Is there a way to remove the spring back on a toyo camera back so that I can use the Graflok back?

I can see the sliders in there, I just can't for the life of me figure out how/if I can detach the spring back.

Thanks in advance.

Push the metal hinges down, then slide the GG assembly UP; hold onto it as you slide up.
