Smart call this "Repair Set - E drive".
Comprises two cables, + 2 special spring loaded plastic parts, some new screws and ONE plastic cog (gear). and a few other essential small parts,
Smart now recommend and fit just the one motor, but it still needs two cables as guides.
The plastic cog is unavailable alone.
So if you really want two plastic coge, you have to buy 2 kits and you will have two cables left as spares.
