Question: Can you confirm the collapsed and extended pin hole center to center distance?

Answer: Finding the correct trim cylinders for your boat's Mercruiser outdrive will be based on year and model of the sterndrive unit not a length. These particular cylinders fit early Alpha and Pre-Alpha drives with internal lines meaning they both enter the enter near one end of the cylinder.
