Trying to find the bore size of the gearmatic 3310 winch controler. Going to fabricate one using clutch master cylinders. I have the option of 3/4", 7/8", or 1" bore. Am trying to get close to original. From what I have seen, I am leaning towards the 1" cylinders. I Ran across a discussion where someone else was going to try this but found nothing on the results or what size cylinders he was planning to use. My fear of going to small is not having enough volume to activate the winch cylinders, or to big and have a hard time applying enough pressure.
Any info/thoughts?
