No. The pivmatics are a trimmed up fiberglass tube with a clam cleat riveted to it. Those other pivioting clam cleats are not very robust. They are ok if you rarely hit the bottom. A friend tried them and they failed after a couple weeks.

Fairly sure the outer tube of a worn out Hot Stick is the same diameter as the piv's. lacking that you could lay some glass up on the tiller tube. Trim it up and install a clam cleat.
