Ok, after looking at mine again, John is right, you don't need a bushing in the front. You have to drill one of the two holes below the big one for that spring retainer thing.That will put it down so you will have a progressive set up. But, after looking at my leftover parts, I still had several bushings leftover that all came in one package.
You know if I knew then what I know now, I would have gotten the whole thing from Scott Harm with his reworked Carter carbs. Then everything works the way it is supposed to without any headache.
