The new one touch system will work in your grill.
If you have Dremel with a cutoff wheel, the easiest way it to cut the control rod off on both sides of the bolt coming out of the bottom off the kettle. You’ll need to cut as close to the bolt as possible. Cut where I’ve circled.
The bolt and blades should fall out. You might need to tap the bolt carefully to get it to fall through.
