Last year, I tried to remove those Phillips head screws, for window latches = didn't want to loosen. (was going to built something, in-between those screws, too)

 I even had an impact screwdriver and hitting it with a 2 lb hammer, and one still wouldn't loosen (=broke the phillips bit), I gave up on that idea, and added a SMV "female" bracket to my drink holder/ash tray. Put sprayer control, onto the "male" SMV bracket, and added another "leg" to stabilize it, against drink holder.

Note: Now, that I see the K&M bracket, it wouldn't work either, with the JD forage chopper controls, in right, rear corner.
