'66 273 BBD Carb

It's damn tough to get those small screws out. Is it steel or brass? Just asking in case someone is damn handy with a tig welder. It might be easier to start a wanted thread and find a used carb. There might be a few around yet from guys that took their 2 barrels off for a 4 barrel. I see a rebuilt or two available as well. More Information for AUTOLINE C679
