Catia V5 Kinematics

Trying to get this assembly to simulate but it doesn't work properly. Anyone able to help? Bonnet should move 60 deg about the hinge point. Gas struts will move with it.

There's an extra DOF, which is common with spherical joints. Add something to eliminate the rotation of the two GasStruts

@jack K - So I deleted the cylindrical Joint, and replaced this with a Prismatic joint, by adding 2 common planes along the axis of the gas struts.
Still the Assembly doesn't simulate.

Ok, I've managed to fix this by removing a spherical joint, and adding a prismatic joint between the cylindrical upper/lower gas struts, a point surface joint, and a Universal joint to lock all the DOF's.
