Here is my guide to retro fitting the cruise stalk from an Alfa 166 to your 4200, Spyder and GranSport. This guide does not include the 3200.
These items do wear so I WOULD NOT purchase a used item, I would only buy new as you will find that the indicator cancellation does not work and that is really annoying believe me.
Alfa part number: 156018005
Difficulty: Moderate

and a further 5 fixings on the underside. both sections can now be removed.
12. Remove the paddle shifter. This is not necessary but I did so as not to damage them
13. Attach a medium 3 legged puller to the steering boss and gently wind it up. It will let go fiercely, so be ready to catch it:

20. This is what you will be fitting is the reverse of the removal. NOTE: you have a new multiplug for the Cruise Control stalk. You have to remove it from where is is mounted on the Alfa part as it will not allow the cowling to go back on. This slides towards you to de mount it:

Refitting is the reversal of the removal.
