Hi Dan,
No some of the plastics are new.
New fitted are,
Front bulk head.
Rear bulk head.
Driveshafts.
Transmission case.
Hinge pin blocks.
Shock towers front/rear carbon.
Hinge pins
Rear shock bodies.
Front hinge pin brace.
Think thats it Dan. I clean all my plastics with Pledge, pre-wash with washing up liquid warm not hot then pledge them.
