Holley carb linkage

So I did a intake manifold and carb swap on my 77'mav. My issue is I do not know how the throttle connects to this new 4 barrel Holley carb. The new carb does not have the stock ball knob that fit into the socket at the end of the throttle linkage. Another problem would be I don't have a diagram telling me which hoses are which that are coming from the car and going to the carb. If any one has a vacuum diagram it would be most appreciated if you posted a link or took a picture....if needed I will post pics later, I'm at work currently

 

Ball sold separately...might have to drill the hole bigger.

Where would I get the ball?

 

Local auto parts store might have the ball stud. They usually come in assorted sizes.

 

Napa has balls

 

New Holleys sometimes have the ball stud in the box.

 

thanks guys i got it from oriley's
