Are you looking for a new switch? Or a used original switch?? Centerline has a re-worked Fiat switch that they sell to replace the Alfa ignition, but make sure you speak to Carl to go over the wiring, as it is a bit different and not a wire for wire replacement. Switch looks OK in the column, but isnt an exact match. Good luck!
I have read here that the replacement (new) ones just aren't that 'good', so I am not sure what it is I want! I would definitely be happy with a quality original one that will give me no headaches or STRAND me when I can't turn the freaking key!!!
