Pontiac Tri-Power Carbs 389 / 421 Tripower 3X2

I have a nice set of factory 1964/1965 Pontiac tripower, 3x2 carbs. They are Rochester 2jet carbs. The primary is a small base and the factory dumpers are large base. They will all need kits installed ($22 online). They have minor pitting in the castings. The butterfly shafts are solid and are not wore out. It appears they were not used very long before they were removed. I have attached two pics and can take more if needed. Looking to trade for a small base Rochester 3x2 setup. I will consider selling outright.
