Most of the new fairing with the dzus should fit to itself so won't be a problem, the two bolts by your knees on the mid fairing will be harder as they fit to the frame where you put the Dzus clips, the top fairing and belly pan fit to themselves
Its easy, ignore what you have fitted as you take it all off and replace it with dzus to fasten top and side fairings together and side fits on dzus anyway. Ignore the mid bolts n the sides, but you do need the one by the stand and opposite by rear brake. Depending where they came from, you may have to remove the airtube covers, I do, which are a real pain but I never put the inner bolt back n any more as thats a shitter to get at I fit mine with; 2 numberplate bolts to fit where the mirrors would be 4 dzus either side 2 bolts at rear back fairing if one piece belly pan (like mine) i have quick release fasteners to its easier to remove if needed at the track but actually just slide it out in one piece to take off/put on the seat unit uses the same stuff so reuse what you have is probably ok
