89 Ranger Diff
 

i have a 89 ranger 4x4 2.9L and need the guts for the gears but i dont no wat gearing it i counted 41 spots for the teeth but theres only 23 on the ring. any one have a idea what the gear ratio would be 3.27:1, 3.73:1, 4.10:1 4.30:1
would i be able to check the gearing on the front wheels?
