I took out the old TV in my conversion van. That left a hole. My husband then put the mount http://www.amazon.com/gp/product/B000ID7QNI/ref=oh_details_o02_s00_i00 on a piece of wood cut to tightly sit inside the hole that was left. I have little eyelet/eyebolt screws above and below the TV to hook a bungee cord to keep everything in place while driving. http://weloveteaching.com/RV/1220021515c.jpg
