I did this work with a Dell WD15. The screw slots only align with 1 hole on the Dell Dock which will likely work without modification. I held a piece of paper over the back of the dock and pressed the paper into the screw holes drilling holes in the paper. Then I held the paper over a metal plate and drilled holes. Metal drill very light. The vesa hole pattern and screws match perfectly, the dock mounting screws also fit the Dell docking station. Mounted on LG 29" ultra wide monitor.
