Yeah as far as I know the K7030 kit would come with standard bushings. The K7103 bushings will work fine with the new eccentric bolts.
That said, the pictures of that kit online show eccentric bolts that have flats cut on both sides of the shaft. Factory bolts only have a flat on one side. Cutting the flat on both sides doesn't leave much thread. Those wouldn't be my first choice for eccentric bolts, assuming the ones you get look like the pictures.
