Strange problem. I'm adding FI to my 455 and I'm setting up the throttle linkage. I need to make the connection, so no big deal I think, I'll just pull the ball off of the old carb. I have two quadrajet carbs. And the ball for the ball and socket joint is of a different size on both! The one I need is riveted to the linkage, the other that I used was bolted on and is too big. So I need to order one, or get a new cable, or something. Any thoughts? Any idea on what sizes were used? They look identical, but they isn't.
We have new 1/4" and 7/32" available. Can you measure what you need? If not, let us know the carb number and we can measure and compare for you. http://quadrajetpower.com/throttle-ball-1-4-new/
