When they aren't missing from the car, these plastic circular bezels/grommets surround each door lock pin.
If you have an off-black interior, you will want to order part 39983010 (the dark grey bushings are distinct from all others).
If your V70's interior is tan or beige: Each "correct" factory replacement bushing is a hefty $9.55 - plus, the two possible colors, Oak/Arena (part 39978890) & Sand/Beige (part 39978892) look similar, so you might need to email us with your VIN to determine the right one. However, we also have cheaper Genuine Volvo bushings (part 39896675) for $3.07 each that look good on both 'Oak' & 'Sand' door panels when used in pairs. They are a different shade, but have the correct fit.
