Missing details for robot lengths?

Hi there.
I am new but there has been a time since I’ve been missing some distances on the details for each robot.
I have seen there’s been a new post with more details for calculations Universal Robots - DH Parameters for calculations of kinematics and dynamics nevertheless I am still missing some distance parameters. I am unsure if they are listed somewhere and I cannot find them. But mostly I am missing the connectors length. Find attached a screenshot with the 3 distances I refer to as missing marked as “???”

Greetings
