All the fisher plows i've had, had single acting hydraulic cylinders. I'd look at that first because i think you'll need to find a different cylinder.

its alot easier and cheaper to make a ridgid thumb that you can just adjust with a pin, and fold against the boom when not in use. you will have a grand into hoses and a valve likely by the time your done. unless your doing alot of work with the thumb a non hydraulic one works just fine.
