Old man with old car, new here with questions

Hello Dan, I received the carb listed on Ebay that you told me about. Cleaned, adjusted brackets and mounted it. I am also changing the fuel line per your write up. Top line fuel injection hose, the inverted flare connector, fuel injection clamps and metal fuel filter etc. I am waiting for the 90 degree swivel connector to connect to the new fuel pump.
I am having a problem finding the proper bushing that connects the throttle rod to the carb. Some pictures show them as one piece. The only one I am finding is a rubber grommet with insert for the first opening of the rod.
Is there an alternate method to hook it up??? Thanks, Hank
