I have yet to find who sells the 4.30's for the 9.75, i know a few companies offer them for the 8.8. I believe i noticed them for the 9.75 aswell just cant find them now.
If you can get 4.30's id go that route, the gain out weighs the loss IMO. Just a couple hundered RPM difference.
for gears check
Yukon
Ford Racing
