TH350 what speedo gears?

Going to a 4.10/4.11 9" combo with 28" tall tires, what speedo gears do I need in the TH350 trans? Also if I end up with 26" or 27" slicks based off my trap speed and mph, what would those combos need as well, the local trans shops in the area don't have a clue and I tried searching around online with no luck.
