to rebuild or replace ?

Let's see if I remember how to get a dam picture to show on a website///IMG_20210729_185839766.jpg
Short black one almost certainly too short for a splitter, almost 4". X 11". But 99% sure that one is new too.
I have 2 more (matching each other) have "IH" stickers and yokes on them, smaller yet than what I have shown. I think they are bucket cylinders for an older utility tractor. I know 100% for sure those are both new and too small for your purpose.
