Screws on my Toyta Camry (UK model) plates are plastic headed and appear to be 'sprung'. That is when I try to unscrew with screwdriver they turn so far then resist, springing back when I release screwdriver. Both front and rear plates are the original plates and have same fitting.
Never came across this type of fitting before. Should I just force the screws? Do these bolts need to be tackled from rear?
