There is a member on this group that makes magnificent Stainless steel Cars.
If you plan on using the Amel cars, make sure you use something like duralac or some other material that will not allow the stainless to corrode into the aluminum.
Personally , I would search the group and find the Stainless cars and keep the Amel ones as a spare.

Subject: [AmelYachtOwners] Genoa car control wheel
On SM 422 (SV L’ORIENT), Ive replaced both genoa car control wheels as they corroded and fractured. This job was complicated by the fact that they were aluminum and in contact with the stainless steel rod mounting, and held in place by stainless steel screws. The corrosion was such that cutting tools were required just to get it off the mounting. I got my replacement wheels from Amel but Im concerned about this dissimilar metal issue. Im hoping someone has a creative solution.
