I had my AC contractor bend me up some sheetmetal just 3/8" over sized of the monitor casing so when I cut the leather and pading I took the monitor case and pushed it into the sheet metal. The only thing i had to modify was the rib stamp into the factory metal head rest. . It was easier for me to unsnap the leather back and pull it over the back rest.you will have to remove the armrest.which was not hard to do.
