After pondering it for a few days I decided that rather than make a bunch of custom mods to accommodate the stab sitting too high I would go ahead and bite the bullet and lower the stab to where it should be. Unfortunately, that means lots of parts to be replaced because the mounthing holes are already drilled. Most of the time was spent opening up the skin to get at the forward mounts and then getting the mounts unriveted. Knowing what I do now, putting it back together so that things fit correctly should be much easier. I know the stab needs to sit lower and farther aft than before. In addition, the new cut of the lower fin skin is cut with a lower edge that extends farther around the curve of the stab than the original, obviously intended to be included in the forward AN3 bolt mounting holes.
