This is the original fixing screw and sleeve-nut inside the original Geco mirror, as fitted to 2cv, Dyane, Ami, Mehari, AK, as well as many other French classic cars.
The price is for one screw and one sleeve-nut.
The other components shown in the photos are available separately.
We also have an alternative swivel kit, which is a cheaper option than using original parts.
