Hi Alan,
Yes, from memory on my 22 , if you lift up the table leaves there should be a hole in each side of the keel box where you can put a pin though the keel box through the keel and out the otherside .you may have to raise or lower the keel a little to align this,
Remember the keel is quiet heavy so be sure to used a substantial pin for the job.
Removal of the table top to access the cable mechanism etc.
Keep in touch
cheers
