My brother-in-law....so, no charge.
You could reach out to him and see if he would make one, and what it would cost. They key measurements he would need are:
Diameter of the shaft, od of the strut hole, and length of the strut.

The guy I helped at the marina had access to some metal working tools I think. His was not quite as well-constructed as mine, and basically had 2 square plates, one with the notch to fit over the shaft, and one with a hole to allow the bearing to push out. Each plate had a bolt hole on each corner to run the all-thread though to squeeze the plates together. Not sure how me had the collets...I think he found a piece of pipe with same ID as the shaft OD and cut it down the middle. His plates were a bit thin, and bent some. Mine are overly thick. Could probably get by with something half way in between.
