Hi JJ. I started measuring the cylinders on my old Cub Cadet's loader and my LS's. It turns out that the CC's 417 loader is probably a Woods 162, and everything is in inches. The LS's rods and ends are all in even metrics. You know from another thread that I have power issues with this LS loader, mostly due to leverage and design. Any mods I can make to improve it will mean changing cylinders, but the mounts are all metric. They are all crosstube mounts. I haven't gotten at the pins to get an accurate measure or taken them apart. They are special bolts, fitted with zerks, with locknuts, and I'm guessing they won't be one inch.
Anyway, it doesn't look like there is any supplier like those that have been linked here that offer these metric sizes. It seems that the only thing universal about the cylinders is the plumbing.
