That's a 2nd generation "universal" speed cal that works on most late model fords with a VSS, the 1-7 pack is to set it for the type of car I believe...
They don't make a speedo gear for 4.30's...4.10's (23 tooth gear) is the highest they make...
If you are looking for the teeth to put in for the DM speedcal calculator, just use 19 if you've never changed the speedo gear to something else...in other words, for 4.30's and stock tires (245/45/17's) you should set the larger dip pack to 1010100001...
