looking at gears to buy , not in box but new and questions??

[2002BLGT]

ford gears says they are 373s and need to make sure ?? how many teeth on ring and how many on pinion gear for 3.73s ????

i think it should actually say 3.73 somewhere on the gear

divide the number of teeth on the ring gear by the number on the pinion. If they are frpp gears it is stamped on the end of the pinion gear.
