Maybe im not thinking of the same type of spring loaded pin you are...
I would offset the pivot point towards the front of the vessel, that way you have the weight of the kettle providing some stability. Next I would put a relatively stiff piece of rubber on the cross beam to damp the contact between the two steel pieces. The pin would just hold it in place, just like you've drawn for the turnbuckle end mounts, it doesn't need to be spring loaded (I was thinking of a 'spring plunger'). If you position it right, you could pin it in place with some compression in the rubber, which would prevent movement and vibration. I guess if you want them REALLY stable, the turnbuckle will work for that purpose.
