I have two related questions regarding a McMaster Toggle Clamp. I downloaded their model, saved the bodies and created an assy. Then I created mates so the thing would toggle.

1) In the sub assy I made I got the levers to pivot around the pins correctly but I can't figure out how to put in the mechanical stops. There are two roll pins inserted into the clamp and they will stop the lever when it hits the pin. How can I get the same effect? I was thinking about using an angle limit but that's not how the clamp really works.

2) in the upper level assy, the clamp sub-assy does not move as it does in the sub assy. Is there a way to enable motion from a sub assy to be used in an upper level assy? I'd rather not build that sub assy inside the upper level assy if possible.
