Thanks Dan. What you wrote before in another thread inspired what I attempted, but reading this I'm pretty sure I didn't do it right. I think maybe I see what I did wrong. Let me look again and maybe get a few pictures.
In the mean time, one question. When the pry bar is in place and engaged with the tab and you are about to apply force to it, is it more or less horizontal/parallel to the right axle? Or is it vertical and perpendicular to the axle?
