I was responding to the gentleman that has a loader with missing cylinders. I do see the issue and it does not look like an OTS cylinder will work there without a little modification.
You still measure the retracted length and stroke just as I described and take the added length of the base end stub into account when buying the new cylinders
A welding ship can weld a stub on there PDQ. Might also want to have a look at something like this. It gets you 2" of base end extension and might actually work OTS.
