While working on my newly acquired 1970 r60/5 I needed to dismantle the rear shocks. After looking around I saw this good for nothing caulking gun hanging in one corner of my shed. Thought the idea might work and to my surprise it turned out to be the best tool for the job. Here is the pictures for the setup. I indented the bottom of the shock with a drill bit to prevent slipping. I hope it might save someone else the agony of compressing those shocks. Thanks!!!
