I am replacing the original Rochester Quadrajet Carb on my 1969 (Chevy 350 engine) with a Chinese knockoff. What size jets would you recommend I use?

I now realize the threads in the carb that take the fuel filter housing are really worn. I acquired a new fuel filter housing but that didn't solve the huge leaking problem. I am now looking for a old timer that can reconstruct the threads in the carb housing for me.

The Rochester Quadrajet carburetor is shot on my 1969 with the Chevy 350 engine that came from the factory when new. Where can I get a replacement with an automatic choke? I am looking for an authentic replacement.
