There is a complete 65 or 66 system on ebay right now for $1600.00 US. Ad says carbs need rebuilt. A set of clone carbs will run you around $800.00 US and 65 or 66 manifolds can be had for 2 to 300 if you want to go that route. Plan on mechanical linkage because the thermo switch is not available for the vacuum set up used with an auto trans.
I have a set of original end carbs correct for 65 or 66. Centre carbs i would need to build up. 65 is the small centre carb with a hot air choke and the 66 is the large centre carb with a by- metallic choke.
