1st. rear spats. i have removed the 2 screws that face forward but the screw underneath is not for coming off and has now rounded off.
2nd. side skirts. exactly the same problem as the spats. its the screws underneath the car that wont budge

is there a technique to remove these screws or am i better to attempt drilling them out and replacing them all?

Violence is the way forward Flat bladed screwdriver between skirts and body
Worth case scenario - you'll need new plastic bits for the (new) screws, which many people here can supply

i can do that. they are the wrong colour anyway so they will be visiting a paint shop before i have to do it all again on the VR4
thank you
