Actuator for quick attach is shorted so trying to replace it, OEM is stupidly priced so just trying to match it up, I am wondering how many lbs force do I need? And it is ok to go with one that will not be fully retracted? I can find one with the right stroke length, but retracted length is short, so was thinking of jumping up to longer stroke. The OEM is 14.5 to 20.5, replacement i'm looking at is 12.5 retracted 20.5 extended.
